Baby threw up in her sleep

Today my little started throwing up so much during her sleep at 4:45 am scared me, I felt all he throw up before I realized she was choking on it and I got her upright and starting patting her back to get it all out. One of those nights I am so grateful we cosleep I can’t imagine her being in another room in her bed and that happening and I don’t hear through a monitor.

She just got her shots 5 days ago, I split them up 3 now and 3 in a month. No fever. I hope she’s not getting sick and maybe she just drank too much milk I’m still EBF.

So scary 🥺
