My ds is 8 weeks old and isn't putting on enough weight. He was born on the 75th centile and has now dropped to the 9th. I am breast feeding him on demand which is 2-3 hourly in the day with cluster feeding in the late afternoon/early evening. I feed him at around 10-11 at night then when he wakes again which is anytime between 2-4. I try to express if I get time but he doesn't sleep very well in the day unless I take him out in the sling or pram and when I do express I get hardly anything, 5-10 ml normally. He's otherwise well with lots of wet/dirty nappies and is very alert/smily etc. I've been told that my supply is low and to top him up with formula (or EBM but seeing as I get so little it's going to be formula) after every feed but I'm worried that this will reduce my supply even more. He also vomits much more after having formula and it seems to hurt his tummy - tonight he was really distressed at bedtime, drawing up his legs and only settled after I'd cycled his legs for a while. I'm wondering whether I should ask for Domperidone to increase supply. Going to BF clinic tomorrow to check the latch etc but just wondered if anyone had any advice. Sorry for the long and rambly post!
