Long post, sorry, with background - I failed breastfeeding with ds1 in 2007 and was very anxious to do better with ds2 born last month. DS2 was born at 4.5 kg (nearly 10 lbs) by emergency CS and while he was quite well at birth, I wasn't, which made focusing on establishing feeding much harder. We went home on day 4, on day 5 the midwife discovered he'd lost more than 10% of his birthweight, and on day 6 he'd dropped even more, apparently a record amount of weight in total. He'd not become ill but probably would have done, and he was taken back into hospital (this happened with ds1 who also had jaundice and was much smaller to begin with, by the time we got out after 8 days he was essentially bottlefed).
This time round a breastfeeding counsellor from the postnatal ward came to see us every day in the ward, and I got him feeding better, but his weight gain on exclusive bf remained very slow and after 6 days in hospital we were told to give formula top ups after every feed. He started to gain a bit and we were allowed out on home leave 3 days later - 2 weeks after birth, and after 9 days. We had to go to the hospital every day at first but now down to once a week.
Just over 3 weeks later, have managed to maintain breastfeeding and am hoping to be able to go back to doing so exclusively - he only had about 3 top ups a day/night last week and only 2 a day this week. Two paediatricians saw him at the hospital last Thursday - the first who'd met us before seemed happy with his general condition, but the second told me he should be putting on 50g a day - this is 350G a week. His actual gain last week was 130g - under 20g a day.
350g seems very high and I suspect it's a figure based on formula. On Tuesday this week, 5 weeks old, he was weighed at the local health centre - different scales - but was just over 5 kg (over 11lb) and his weight gain if that's accurate would have been about 30g per day. We were seen by our health visitor who is fairly sympathetic to breastfeeding and even she said the hospital were "mad".
I'm bf on demand and I'm quite hazy on intervals between feeds and their length (very variable but often intervals during the day are quite short, length can be a 5 minute snack or half an hour or more sucking). I'm asking dp to do the top ups, because they're always preceded by bf.
Would welcome an idea of reasonable weight gain for a large at birth, mostly breastfed baby at 5 weeks, and advice on how to handle the conversations with the paediatricians.
