Hi, I'm using Bonya milk by Kendamil. I've noticed it's very frothy and bubbley. My two girls have both been red in the face, crying, been very sick (projectile vomiting) and unsettled after their feeds. Could this be the problem? It's really stressful as I sit them up for atleast half an hour after a feed and wind them (even though they aren't bringing up much wind) and when I think they've settled I lie them down and they're choking on their sick sometimes. I feel awful as I don't know what to do for the best or to help them.
