My sister called me today. Seems my niece (who turned 5 months old today by the way!) gave everyone quite the scare yesterday. Sis was in the shower and had niece in her seat in the bathroom when sis heard niece make some funny noises. When sis checked, niece appeared to be choking. She eventually quit breathing and started turning blue. 911 was called and by the time the EMT's got there niece was breathing again. But the EMT's said they though niece had a "strange breathing pattern", suctioned what appeared to be mucus out of her and put her on oxygen before taking her to the hospital. At the hospital, niece vomited what sis described as white (or yellow...not sure which) foamy stuff that could have been more mucus. A chest xray was done after the vomiting but nothing showed up and they sent her home. Sis called her regular pediatrician today but they said it was a simple choking incident and didn't need to see the baby. Granted, while I've been around babies, I haven't had one of my own but this still sounds really strange to me. I asked sis if niece had been sounding congested or anything and she's been fine. She had nothing within reach or in the seat with her that she could have physically choked on...sis is very anal about that. Has anyone had a similar experience or have any thoughts?
