Hi
Our baby (Austin) had been breast fed with expressed milk up until 3 months. He had been regularly taking 160ml-200ml each feed (3 hourly). He had been sleeping through (on breast milk from 8pm to 6am) from 10 weeks.
We had to switch to formula feeding at 3 months and after a day or so the pattern began: More and more he would refuse part way through a feed (it started at 120ml ish and is often now down to 70ml). It seemed silent refluxy (he suffered from refulx earlier but it had gone by 3 months) he stretches his back out pushing with feet (not arching), goes red, grunts and pushes the bottle away. This happened most in his morning/early afternoon feeds and he didn't have a problem with his 7 & dream feeds. We tried feeding less frequently and moved to a 4 hour routine. This made little difference. It's like his body couldn't process the food in the morning (I know it takes longer for formula) to make way for more food as he never cried for food at this stage (he would always let us know before). We added a dream feed which he demolished 200ml every time and carried on sleeping through (even though his total over the 24 hours had gone from about 900ml-1000ml breast milk to 700ml-800ml formula).
He is now 16 weeks old and things have got worse. He is on Ranitidine 1ml x 3 a day (a high but not top dose for his weight) and signs of silent reflux seem to have gone pretty much but the eating problem still remains in the morning and i'm not sure it ever was reflux?! In the last few days he has suddenly started to take massive amounts in the afternoon/evening and started waking every three hours during the night for food. E.g. Yesterday had 270ml at 3:30pm, 50ml at 5:30pm (split feeding pre-post bath) 190ml after bath, 200ml at 10pm, 200ml at 1:30am, 100ml at 4:30am and then at breakfast (7:45am) he ate 40ml. It is not sleep regression (yet) as he goes back 5-10 minutes after feeding in the middle of the night and gets himself off and stays asleep till the next feed.
It's like he is on a 4 month growth spurt. All other spurts he has been on he has ate loads more during the day and carried on sleeping through. I'm just very concerned this could end up with him being used to eating at night, needing to eat at night and undoing all the hard work we have done with sleep training (he gets himself off without even a shush or pat most times during the day and will mantra cry at night but then get himself back) and also kill our energy...
It also sounds like it's his body in the morning that is the root of all this - just don't know how to get him eating again then. Any help would be very gratefully received.
