Will Formula Help My Baby To Sleep Better At Night?

Whether you are breastfeeding or bottlefeeding, your baby is going to wake throughout the night.

Unfortunately for new parents, long stretches of uninterrupted sleep are a developmental milestone that babies aren’t meant to reach until at least 3 months of age – maybe not even until 6 to 12 months.

While babies do sleep a lot – between 12 and 20 hours a day – they’re programmed to wake often, rarely sleeping longer than 3 hours in a row.

Small tummy size, short sleep cycles, and an immature nervous system all contribute to waking, whether or not the baby is breastfed.

Well-meaning family and friends might tell parents of a breastfed baby that giving “just a little formula” will help their baby sleep better (or longer) at night. And sleep-deprived new parents are eager for anything that might help them catch up.

Will Formula Help Baby Sleep At Night?

Should you follow this path? Will it really work?

Surely it couldn’t hurt, could it?

Here are 6 reasons why you may want to skip that route and breastfeed instead:

#1: Your Breastmilk Supply May Suffer

A supplemental bottle – whether it’s filled with formula or expressed breastmilk – decreases breast stimulation. The baby isn’t nursing, the breast isn’t stimulated, milk isn’t removed, the brain tells the breast to stop making so much milk.

It’s a negative feedback spiral that is difficult to reverse. And if baby is sleeping longer stretches, additional feedings might be missed, adding to the signals that a mother’s body should shut down production.

#2: Your Prolactin Levels Are Higher At Night

Take advantage of your daily hormonal fluctuations! Prolactin – the milk-making hormone — reaches higher levels at night, so breastfeeding at night helps keep your milk supply strong.

#3: Breastmilk Is Easier On Baby’s Tummy

Anything other than breastmilk disrupts the delicate balance of baby’s gastrointestinal tract. A breastfed baby’s gut is colonised with beneficial bacteria that help to keep baby healthy – this is the host site of the developing immune system.

Formula changes the types of bacteria present in the GI tract, potentially disrupting the process. In addition, breastmilk is extremely easy to digest. Formula, on the other hand, is harder for baby’s body to process.

This may be why baby seems to go longer between feedings, but it can also be the source for discomfort, gassiness and fussiness.

#4: Long Periods Of Deep Sleep Increase Your Baby’s SIDS Risk

This is essentially what you’re trying to do when you give your baby formula at night – you’re trying to force your baby to sleep longer than the body is prepared to do.

This may be inappropriate for young babies, who need to wake more often to regulate normal bodily functions such as respiration and heart rate. Researchers think that breastfeeding at night helps this happen – babies wake because of an empty stomach and these wakings maintain other essential functions.

#5: You Run The Risk Of “Nipple Confusion”

Trust me … your baby’s not confused. Your baby quickly learns that there’s a difference in flow rate. Not only that, a baby uses his tongue differently with a bottle than when at the breast.

While some babies have no trouble going back and forth between breast and bottle, others come to expect the rigid stimulus the bottle nipple provides and can’t figure out what to do when offered the breast. Find out more about nipple confusion.

#6: You May Unintentionally Wean Your Baby

If your milk supply dwindles from supplementation, and your baby begins to have difficulty latching, you may find yourself supplementing more and more often – and not just at night. All of a sudden your baby may no longer be nursing at all and you wonder what happened. A bottle of formula at bedtime can start you on this slippery slope.

So What Should I Do Now?

If formula isn’t going to help you catch up on sleep, what can you do to make nighttimes a little easier on you?

  • Consider sleeping with your baby near you – put the crib or cradle in your room so you don’t have to run down the hall to get baby during the night. Keep the lights low, and minimise stimulation during nighttime feedings.
  • Nap when your baby sleeps during the day – don’t use that time to catch up on housework. If you can’t sleep, at least try to rest.
  • Alter your own expectations – think about your own sleep habits. Do you wake occasionally to look at the clock, sip some water, go to the bathroom, snuggle with your partner? Babies just need our help to do these same things.
  • Maybe most importantly, stop comparing your baby to others. Every baby is unique. Your baby will sleep longer when his body and brain are ready for that milestone. Until then, enjoy the cuddle time with your little one.

  1. The amount of pressure that woman place on themselves in regards to this is outrageous.

    Many babies for whatever reason are bottle fed and they grow up to be strong and healthy. When was the last time you applied for a school, signed up for a sports team or even had a job interview and you were asked if you were breastfed or bottle fed as an infant?

    It isn’t the milk that matters it is the parenting! This article enhances fear and nervousness in already anxious parents.

    Please if you are not coping and searching the internet for questions such as above, go and see a doctor and get sound medical advice that is right for your child. Don’t go off the advice of a blog that just wants people to read their articles because they make money from it and the more controversial they can be the better.

    I hate this website because of the clear one-sided rubbish that is written. Do what is right for you and your family to be a successful and happy unit.

    The milk doesn’t matter! It is the parenting!

    1. Mike, you did know that doctors have no lactation qualifications, and only around 0-3 hours in information? I have written about it here after speaking to many medical professionals. It’s a problem all over the world.

      The above article has been written for breastfeeding mothers who are told erroneous advice that formula helps babies sleep more. Even formula feeding mothers will tell you that it’s not true – their babies wake just as much too. Wakefulness is biologically normal and necessary – tending to babies is a responsibility as a parent. It’s tough, but it will pass.

      Hate is a strong word, I am curious why it pisses you off so much, when all of the advice written is from highly experienced professionals (in this case, an IBCLC which is the equivalent to a Masters in breastfeeding – something no other professionals have) and you can simply ignore articles like this which trigger your emotions. It’s factually correct information, backed by research and science and given from the highest qualified breastfeeding professional possible.

      I an assure you, I don’t do what I do to make money. The website came first, then the advertising to support the running of it. If I wanted to be wealthy (from a monetary perspective anyway), I would have been better served working in pharmaceuticals! 🙂 But my passion is to inform and educate amid a great deal of misinformation, which is fuelled by intense emotions which impact decision-making. Not to collect pieces of paper.

  2. Thank you for sharing all this useful information. A question though : not regarding all you say in favor of breastfeeding, is it true that formula helps babies sleep better ?
