Hi Fufulina,
Congratulations on your new daughter!
I have a new son (first child) who at 6 days old is exactly the same!!!! I worry that feeding so rarely is detrimental and have seen 2 midwives and a maternity support worker all for advice re the feeding. The problem, I find is that everyone has a differing opinion and I am just trying to do the best for my beautiful son.
With this in mind, I last saw the midwife yesterday and my sons weight has dropped from 3780g (8.3lbs) to 3500 (7.7ilbs)feeding anywhere between 3hr and 6hr intervals. I shared your concerns, however having spoken to the midwife NICE guidelines in conjunction with UNICEF suggest a healthy (tick) good colour (pink = tick) can be fed with 6 hr intervals.
My midwife suggested she would only be concerned if he had lost 10% or more of his bodyweight. He hasn't and neither has your daughter.
Has your milk come thru properly (mine has but only today) and we keep have to have little chats about trust, "I am your mummy and you have to trust that I want the very best for you, but you have to trust me that you need to feed like this" as I to am "blessed" with large breasts. Sometimes the chats work, other times not!
Also what about his nappies, are you having to change him regularly and what colour is her poo? If black like when first born, speak to either your midwife or a breast feeding support worker (ie la leche) but my sons have changed from black to a kind of yellow sometimes green colour and I am assured that this shows signs that he is digesting what pitiful amount he will accept from me.
Finally, whilst I am breast feeding upon demand, this is being dictated to by him. I am not waking him as I NEVER thank anyone who wakes me for a feed! Also like your daughter, if he doesn't want to feed there is absolutely nothing I can seem to do to persuade him otherwise.
Is your daughter crying, my son isn't just sleeps tons and my mother has suggested that he seems content with his lot and whilst I am fretting, he is simply growing!
Follow your instincts as my midwife said (easier said than done)- it appears my son, asks for food when hungry but otherwise is happy to stay in the land of nod!
I hope this posting helps, let me know how you get on. This is one of my more rational moments but I still have my moments of doubt, where I think I should be feeding every 2-3 hrs and I should be able to get him to feed but I can't.
Finally, I had no idea bf would be quite this stressful.
