Not eating much during the day?

DS is formula fed and not yet having solids. He would usually have 120mls every 3hrs or so, its says 240ml for his age but only occasionaly will he drink that much.

In the last few days its a struggle to get him to drink his bottle.

Yesterday he only had two bottles (360mls all up) between 10.30am and 7pm! He had a tiny amount of water also, maybe 15-20mls.
He woke up 4 times last night and the first time about 1am and had the whole 240mls, next time was 180mls and the last two times only about 30-40mls.
Now since 9am today he has only had 180mls and its 4pm!

He is still happy and sleeping like normal.
He is having the 'right' amount of wet nappy's, just a bit less than normal for him.
and Doesn't seem hungry.

I know the weather has been warm, so i put it down to that yesterday, but its alot cooler today and not hot at all inside.

I have recently changed him to the S-26 Gold progress formula (step 2)....Could this be a reason why?

I don't know much about formula but I've heard it said that babies don't starve themselves - it's not natural. Maybe he had an off day and has mucked up his rhythms so he's taking more at night now, and not hungry during the day? If it were me, I would probably try to only give small amounts if he wants something at night so he starts the next day with an appetite. When DD wakes in the night, I try to get her back down with just one side for that reason. Good luck Jess. :)

Thanks Sacha, I will try that, just giving him a smaller amount at night is a good idea then he will wake ready for a bigger feed.

The first time Charlie did this i didn't know what was happening, but he hadn't had any during the day so I fed at night. it lasted a few days & i tried my hardest to get him to feed during the day....then all of a sudden 2 teeth popped through. This was around 5.5months....so your bubs could be teething. At the same time he got a snotty sounding nose, woke regularly at night, & red cheeks. I now know the signs, so perhaps it could be that. It hurts so they are often off their food, but go looking for it at night. If bubs hasn't had much during the day I prob would give what's needed at night or you could just get more frequent wake ups. If it's getting used to new formula then it will settle & bubs will get himself back on track. If its something like teeting some get etc during the day to ease pain that might help with feeding more & something at night might create less wake ups. HTH.

I didnt think of teething as he has been happy, but i have wondered when his teeth are going to come and now i think of it he has been a bit snotty sounding for a few days. He has been chewing on things alot, so i will try some gel JIC.
Thanks.
