Hi - my 13 day newborn has scared the bejesus out of me twice in the last two days. About 20 mins after a feed she's vomited massive amounts through her nose and mouth, then turned red and screamed the place down - seemingly finding it impossible to breathe. She eventually catches her breath and calms down, but it's really, really scary and I'm now worried about putting her down in case it happens again. She seems really distressed by it.
Any ideas why it's coming up through her nose and what I can do? Help gratefully received!
