I think I may have done a very silly thing. My baby is 12 wks - he's a big boy - and I've been reducing his topups, he had his tt released at 3 weeks but has never been that great a feeder. I've been succesfully pumping to increase supply and wondered whether he was up to maintaining my supply so I stoppped pumping...supply went down and he wanted more formula. After 120ml he would cry but I would burp him and put him back on the breast and he would settle. Anyway this week after 3 days of no poo and then a green one followed the next day by something ochre rather than those lovely yellow coleman's mustards, I was worried I was underfeeding him. I just read 'The Essential First Year' and she says an empty bottle could indicate underfeeding, give them an ounce or two more and let the baby decide. So after his 120 today, I waited 30mins and offered him another 120 (made up already in fridge) HE DRANK THE LOT! and cried when it was done. The teat has one hole so it doesn't pour down, he has also cried after 120 through SNS finished. But then 5 mins later he cried again and this time it was more I don't feel well - so how can I tell if he's really hungry? I'm so scared of seeing those skin and bone limbs that I thought I was overfeeding him and now I worry the other way. It's so difficult to find the right balance when using topups and I know he can't demand more from me, he's tried but his suck is just not up to it. I rather increase the frequency of topups than amount but anyway I'm back to pumping to increase and keep up supply until he's up to it.
