Breastfed DS (first DC) was born on 17th November and weighed 5lb 11oz. He was 37 + 2 weeks, although the hospital actually adjusted his gestation to 36 +5 after a growth scan the day before he was born. I had pre-eclampsia and the midwife who was at the birth (I had an emergency c-section) said the placenta had been in a very poor condition.
DS dropped then down to 5lb 4oz 5 days after birth, increasing to 5lb 10.5oz by day 9. I was then discharged by the midwives, and he wasn't weighed again until day 18 at the first meeting with the health visitor when he had only got to 5lb 12.5oz. At this point I was only feeding him roughly 4-hourly (he was jaundiced and therefore quite sleepy, and I am inexperienced). HV was very concerned about this, which seems fair enough, and suggested feeding at least 2-hourly as well as giving a few tips re latch etc. I took all the advice on board and when he was then weighed 5 days later he had gone up to 6lb 3.5oz. HV content, I was obviously very relieved.
Anyway, HV has just visited again (8 days since the last weigh-in) and he has only put on 5.5 oz, so now 6lb 9oz (and he had the filthiest nappy ever just before she came - could that have amounted to another couple of ounces if she'd happened to weigh him beforehand?). HV is very concerned about this insufficient gain and has gone off to ring my GPs (not affiliated with my HV at all) to get their advice as she thinks there could be something wrong with DS causing him to not put on enough weight and she is going to get them to ring me as a matter of urgency - N.B. there are currently no other indicators of anything wrong with DS. She also wants to weigh him again as soon as possible because she's so concerned, but because of Christmas this won't be until next Thursday now. Obviously this is all quite upsetting, and I'd really appreciate others' opinions on whether this situation is as concerning as the HV is making out. I appreciate that DS is still very small, and I really want him to get bigger as quickly as possible, if only to make him a bit less vulnerable, but looking again at his red book since she left, he has actually put on 1lb 5oz since 22nd November - is that really so terrible? I know that there was a blip between days 9 and 18, but I'm sure that was all my fault for just not feeding him enough.
Also, HV will not consider DS as a pre-term baby and he is therefore now only on the 0.4th centile of the unadjusted weight chart. It is obviously arguable as to whether or not he was born before or after 37 weeks, but I can't help wondering if the fact I had pre-eclampsia and the placenta was failing ought to push him onto the pre-term scale anyway?
I'm feeling really worried about this now and I'd be really grateful for any advice.
Sorry for the garbled essay - thanks for reading.
