I have a 9 week old and he's a snacker, all day he snacks rather than feeds. However I know he can take a big feed as he wolfs down around 150ml in the middle of the night. The max for a daytime feed is 90ml though, occassionally as little as 40ml (mid-morning). It's not a hunger thing as even his 7 o'clock feed he eats about 80ml, then again at 9.30. He's a good sleeper, sleeps 7.30-3am, eats about 150ml+ (in minutes!), then sleeps to about 7.
A day could look like this (roughly)
(night 140-180ml total)
7am- 90ml
9.30am-40ml
11-70ml
1pm-80ml
2.30-60ml
4pm-90ml
6pm-70ml
7.30-100ml
It totals to a good amount for a 9 week old 11 odd pounder. He's definatley grizzingly for food, nothing els will sate him and after his snack he's content. HE is also definately done after as little as 40ml, pokes his tongue and and cries if you push it (obviously I don't!). HV is on about 150ml feeds now, he doesn't eat much more than as a newborn, just more often. MY husband one day tried to stretch his feeds but this just resulted in him undereating as he still stuck to 90ml after 3-4 hours.
So ignore HV? As a footnote he has been unwell, possibly allergic to cows milk formula (I couldn't bf, severe reflux and other issues) so now on soya, seems to be happy.
Anyone elses dc do this/ did this? He'd starve on GF routines!
