This is exactly us and it’s so hard especially when there’s already worry over his feeding from previous experiences.
My son would also have 120-180 happily and went down to 20-50 per feed for a few days.
When he did this I’d stop - as you did - get him in the buggy and go for a long walk (1-1.5hrs) then get home, play, wait for him to cry for milk (usually would take 3-4hrs) then feed him.
I used to hate waiting for him to cry but I didn’t want to jump the gun thinking “he’s only had 2oz he must be starving! Drink!”. Also being out the house took my mind off it.
Friday he only had 6oz from 11pm-1pm the following day, but he was happy, content, not dehydrated and the next day he took more.
I know it’s so hard but keep at it, push his next feed back to 3hrs since the last unless he’s upset from hunger (You don’t have to do this but it worked for us as he then didn’t feel pressured to drink), if he was showing he was hungry before 3hrs I’d feed him.
I find if I give him a cold teething toy and he really chomps it’s his teeth, if he throws it away he’s hungry. So I’d try that too if you haven’t already.
I also stopped keeping on offering him the bottle as I found it really wound him up and just means at his feeds now he’s really hungry (yesterday was 4 1/2hrs between feeds) & ready for it so he doesn’t mess around.
Is he still constipated do you think?
I have also given nurofen on bad drinking days and that has helped, I find calpol didn’t really touch his teething pain.
You’re doing all you possible can so keep at it he’ll pick up drinking soon
As long as he’s weeing as normal try not to worry too much.
My doctor told me the other day the threshold for dehydration is so so low (not sure if that’s a worry of yours but it was for me) and as long as his intake doesn’t drop to 50% of his ‘normal’ it’s ok.
For baby Ro his intake is around 850ml on average so that meant he could afford to drop to 425 which he never did but he did drop to 515 a few of the days!
