My LO is 16 weeks and breastfed and about 3 weeks ago he began waking in the night for a feed again after sleeping through since he was 8 weeks. When I spoke to my HV 2 weeks ago she suggested topping up with 3-4oz of formula as he wasnt settled in the day for more than an hour at a time. It was put down to a growth spurt. However, I'm sure he's finished his growth spurt as he's much more settled in the day and will go 3-4 hours without wanting a feed if I top him up with formula. He's still waking in the night though and now its twice, maybe three times instead of just the once. When he was a newborn he would only wake once in the night for a feed so this is really unusual. Also, last night just before his bedtime, for what seemed to me and my DH as no apparent reason, he started screaming, I tried some bonjela as he's teething but to no avail. I offered him a breastfeed from both sides but again to no avail. I tried winding him but nothing. I asked my DH to make me a bottle and he took it straight away and settled right down for bed. That quite upset me as he didnt settle for me. Whats going on? Is he waking because he's hungry and obviously not getting enough from me at all anymore? He's not putting on as much weight as he could either from me and has dropped from the 75th centile to the 25th. He's having regular dirty/wet nappies and is bright and alert for the majority of the day with only 45 minute naps twice maybe three times a day. I would love to continue breastfeeding until he is at least 6 months if possible and have tried everything to increase my milk supply, including cutting out the top up feeds for a couple of days. And yes, I do feed from both breasts and wait until he has finished feeding from one before moving onto the next. Any advice much appreciated.
