I can't stop crying, it was so frightening. I'm thinking I need to make a doctor appointment to be on the safe side.
He woke to be fed at 7.30am and about an hour and a half later, was falling asleep again. I put him down in his crib and went downstairs. When I came back upstairs to check him twenty minutes later I could see his arm waving in the air as I approached. When I got to him, his face was smushed into the bumper...it looked like he had been tugging at it because it had come away and he was sort of tangled in it. I pulled him out and his lips were starting to turn to blue, he was pale and his back was sweaty...he was breathing. I held him near an open window for fresh air, opened up his sleepsuit and soothed him, although he wasn't upset - he seemed a bit stunned and was breathing heavily (he also has his first mild cold at the moment). He did shake a little and then regained his colour and just seemed sleepy.
I kept him awake because I was scared and then he was as smiley and responsive and alert as usual after about ten minutes. He seems absolutely fine now but I'm terrified his temporary lack of oxygen has caused some minor brain damage...how will I know? How would a doctor know? I'd never forgive myself if that was so.
I've removed the bumpers and will get some mesh ones or something.
