My son is 15 days old today. 4 days after the birth he had lost 275g of his birth weight. 3 days after that he had gained 60g, but he only gained another 20g over the next 8 days and today (1 day later) he's actually lost 40g.
He falls asleep a lot at the breast, so even though feeds were taking 40mins-1hour (1 breast) he wasn't actively sucking for all of that time. The HV said to feed him every 2 hours for 10-15 mins a side, then express from both breasts and try and top him up with that. I've been doing that today and the main result has just been that he now cries inconsolably after each feed because he seems unsatisfied. I'm expressing hardly anything - less than 25ml so far today - and have only persuaded him to take the bottle once.
He also hasn't pooed in almost 20 hours now, although he is still peeing frequently, so obviously there's something wrong. He slept 9 hours on Sunday night, which might be the cause of the loss, but I was waking him up every 3-4 hours last night to feed.
Feeling a bit tearful and desperate - any advice?
