DD is 15 weeks and on SMA gold. She sicks up large mouthfuls of milk, which usually smells really acid, hours after a feed, especially when I change her nappy. Also, since I stopped putting lactase in her feeds, she only poos once a day and it has the colour and consistency of greenish grey clay. I spoke to HV about it, because I thought dd was constipated. HV thought that dd had a slight stomach bug, but that was two weeks ago. I don't want to go rushing to see HV again if I'm just being paranoid.
