Polka, day 4 was the day I melted down and was rescued by a neighbour...
Nazly, my supply seems to have improved slightly. I was pumping constantly all weekend and I think it may have helped. Its also possible it went down due to me (and DS) now having a wonderful dose of flu. Plus I have taken Fengreek since Sat. Whichever it is, things seems to have improved. I got off around 1000ml yesterday, and I've had a good start already this morning. DS is eating 900mls a day though which is apparently top end for a 1 month old according to Kelly's Mom website. (Clear he is a greedy little fucker!)
I spoke to the HV yesterday regarding feed sizes and the lack of information / conflicting information I'm being given/finding. She very helpfully told me, that based on DS's weight using the formula she has for calculating how much a baby should eat in a day, that he should have 450mls. He was eating considerably more than that before there was concern about his weight gain being slow and I increased his feed size! She back tracked after I told her what he was having, and said to carry on as I was doing it right as he has gone from 7lb 6 last Thursday to 8lb 6 yesterday which she was pleased with. She told me to ring them if I had anymore questions about expressing (?!)
It really does highlight how little support there is for expressing. I find it nuts if they are really committed to 'breast is best' over formula as this is a half way house and there are loads of practical reasons why women might want to part express even if they are breast feeding. Its frustrating. And its not much better online either, which I find even more surprising.
I did find an online guide that suggested a feed for a 1 to 2 months old, should be about 120 to 150mls of milk for each bottle. And by 3 to 4 months of age, this may increase to about 150 to 220 mls per feed. But it does depend on the baby and some need more feeds than others too.
DS is 1 month today and on 100mls, 9 times a day. So 120 - 150ml seems about right to me (He's draining a bottle pretty easily, so I think we will be upping his feed again in the next few days).
