Breast-feeding Increases Sleep Duration of New Parents.

OBJECTIVES: This study describes sleep patterns for mothers and fathers
after the birth of their first child and compares exclusive breast-feeding
families with parents who used supplementation during the evening or night
at 3 months postpartum. METHODS: As part of a randomized clinical trial, the
study utilized infant feeding and sleep data at 3 months postpartum from 133
new mothers and fathers. Infant feeding type (breast milk or formula) was
determined from parent diaries. Sleep was measured objectively using wrist
actigraphy and subjectively using diaries. Lee's General Sleep Disturbance
Scale was used to estimate perceived sleep disturbance. RESULTS: Parents of
infants who were breastfed in the evening and/or at night slept an average
of 40-45 minutes more than parents of infants given formula. Parents of
infants given formula at night also self-reported more sleep disturbance
than parents of infants who were exclusively breast-fed at night.
CONCLUSIONS: Parents who supplement their infant feeding with formula under
the impression that they will get more sleep should be encouraged to
continue breast-feeding because sleep loss of more than 30 minutes each
night can begin to affect daytime functioning, particularly in those parents
who return to work.

Great Barb! So good to see something to de-bunk the myth that FF babies sleep through the night, as opposed to BF babies who don't! It really bugs me when people say that, because it obviously isn't true!

I must say, I had a very frequent waker/feeder, but never really felt the sleep deprivation (I didn't catch up through the day either.. not a big fan of day sleeping except when I'm pregnant!).. and I totally put it down to the lovely sleepy hormones that come with breastfeeding.. so whilst I had to get up plenty of times per night.. I didn't really have to wake up fully.. and often fell back to sleep either whilst feeding, or straight after with no problems.

I think if I had to prepare a bottle, and then try to settle the baby back to sleep without boob.. I would have been more awake, and felt the sleep deprivation more.

Very interesting - thanks Barb!

Chelsea has slept thru the night since she was around 8 weeks old and she is FF. I dont believe thats the reason why though. All babies are different regardless how they are fed IMO.

True Kimbaz, but studies can show a trend amongst bigger numbers... so we might know a handful of mums experiences but big studies can spot trends in larger trials. I was talking to a FF mum today and she told me that on her mum's advice she started FF and it didnt make a dent in the child's sleeping (or lack of!).

I'm not sure if it's a thing about the baby sleeping through the night at all to be honest. They were talking about the parents, so think of it this way (in very general terms)....

BF mum gets up, whips out a boob & you're off, then puts bub to bed & nods off herself, no need to fully wake up really. (Although not being able to BF first time I'm not sure if there is anything else in there?).

FF mum gets up, goes to the kitchen, gets the bottle, heats up the water, mixes the formula powder in (which has to be exact), feeds baby, puts baby back to sleep, back to the kitchen, rinses the bottle, back to bed. You have to be totally awake to measure of the formula or you're in trouble & it takes longer to get back to sleep from fully awake.

So yep I definitely agree with the study!

Thank God I breastfeed then, because I really do get a crap night sleep in with Tehya.

Sarah, can't you make up the bottle before you go to bed for the night hun and put it in the fridge ??

Fingers crossed for both of us that these next bubba's sleep good.

I can see this as I had to comp feed Maggie early on along with feeding her ebm. There were some nights at 3am when I realised that I had no bottles left for the next feed, so once I got her to sleep I had to stay up washing and sterilising. I did have the formula pre mixed up for the feeds, but I still had to boil the kettle and wait for the bottle to heat.

both my boys were formula fed and sleep just fine!
Austy slept thru the night from 6 weeks of age and slept for 3-4 hours in the day and Jensen sleeps all night and has two separate naps during the day and he has been just on formula.
I say bring on the formula!

when Jack was still waking for a bottle, we were up and back to bed in 15mins and out to it like a light so I dont see how it makes any difference



besides 1/2 dozen times and when he has been sick Jack has slept thru from 10weeks whether it is because he is f/f I dont know or the fact he is a placid calm baby

I dont think it matters whether bubs is b/f or f/f I have friends who f/f and ones who b/f and they all have problems the majority of them are still getting up to feed and our babies are aged between 1 last may to a 1 week younger than Jack I personally think it depends on the baby not the method of feeding

I think it's an important myth to dispel though that swapping to formula helps with sleep - it doesn't - just like some FF babies sleep through early, so do some bf babies...

I think this is an important point, that people shouldn't assume swaping to ff will help bubs to sleep through.

I ff and this was certainly NOT the reason I swapped from bf to ff.

I don't agree though that I get less sleep, in fact I think I get more. DD was more unsettled during the night when bf, although it was when she was newborn and also my DH does a couple of night feeds, usually the weekend so I can sleep through. We also prepare our bottles before going to bed at night, so I only have to heat it up, which happens when I am changing DD, so I don't think it takes that much longer.

Hands up here - I had a bf baby that slept through the night from 6 weeks! So I agree that you don't need to introduce ff to get them to sleep through. I think it depends on the baby too. Now baby no 2 is 11 months, also bf and still doesn't sleep through very often. So they are all different.

I don't think this study is saying that babies are all the same and bfing is always going to give more sleep. What it IS saying is that it's a myth that supplementing with formula at night will make baby sleep better. Sometimes it will, often it won't. And that's important for people to know, because the first advice given to mothers of babies who are not sleeping through is to supplement with formula at night. The advice comes from grandparents, friends, even MCHNs and doctors. And often, by introducing the bottle, bfing suffers, and the baby doesn't sleep any better. So then there are mums who are not getting any extra sleep AND are stressing and grieving the deterioration (or even the end) of bfing before they were ready. That doesn't help anyone. So if a study has been done which shows some anecdotal evidence that ffing isn't the panacea for sleeping through that it's touted as, then make it known! Let people know so they can make more informed decisions, especially when they are tired and vulnerable.

As a Mum who FF, I have an avent cont that keeps the correct amt of formula in it ready to go at night, I have never heated the bottles it's not actually necessary & it's harder when out if you can't heat a bottle & that's all bubs is used to. So I have the bottle & cont with formula on my bedside table (no need to go to Kitchen), mix it, shake it when bubs wakes up then feed. I'm done & in bed back to sleep in less than 15mins...he scoffs his night feed. We have a recliner & I close my eyes & doze whilst feeding. And I'm lazy, the bottle gets a good wash in the morn, not that night LOL.
Yes I agree with what the study is saying, just wanted to point out that if you are organised etc it's not such a huge task at night time. And if bubs is in own room regardless of BF or FF you still have to get up, get bubs & regardless of how bubs is fed they always have to be put back to sleep. Doing it on their own or not is a different story.:)

Not to mention the times where you lose track of scoops and have to start again. Or when you overheat it and have to contend with a screaming baby whilst holding the bottle under running cold water to try and cool it down ;)

Trish - I don't think you are supposed to heat the premixed formula in the microwave - apparently it can damage some nutrients... So you should heat the water first, then add the formula. Mind you, I didn't know this fact until a looong time after Aidyn went on formula.

Or Ambah you can reheat it as per expressed breast milk but it takes even longer. So yes Trish you can make them up prior to using them, but I never did.

our little bubs is EBM and FF and it doesn't really take that long at night - all her bottles for the night are prepared and placed in the fridge, When she wakes they get heated to room temp. It prolly only takes me a few mintues to get a bottle at night.

I do admit it would be alot easier if she would attacth then i wouldn't have to leave the room at all.
As for sleep we get about 8hrs a night at the moment - thats with feeds.

I think its like most have said it really depends on the baby.

Imagine those of us who do both. I was trying to both ff and bf during the night for a few months. I ended giving up on the a few weeks ago because I was getting so much less sleep. I now jsut FF her at night. I have a bottle warmer which I keep the water in and just add the formula to. She's such a slow eater and we are using slow flow teats so it takes her about 30mins or so for a feed at night. And I don't rinse the bottle in the night either I do it first thing in the morning. But all up I would say I am awake for about 45mins or so, then I do find it hard to get back to sleep again. I am greatful she's only waking once in the night now. A few weeks ago she decided it was time to wake 3-4 times and I was buggered, that's why I gave up on bf at night too.
