Hello everyone! We've been at it for 12 days now, my little one is spitting up a huge amount of milk according to me. It's like a fountain, running from her nose. Once a day, consistently. Sometimes when I'm not around, I'm afraid she might choke. She spits up not immediately after feeding. I raise her after feeding to try and induce vomiting but it doesn't help, there's no vomiting, so what do you suggest? She poops well. Her stool is also watery in my opinion, first liquid then yellow poop. I'm starting to freak out ?
