Hi! Our little 4-week-old girl has difficulty going to sleep lying flat on her back, but when we put her infant seat in the crib and put her in it, she is out like a light. She spits up an awful lot, especially when she is on her back, and I suspect that the angle of the chair is helping her not to upset herself by spitting-up so much. We do not use the "vibrate" function on the chair, and it does bounce a little if she kicks, but she is asleep so fast in the chair that I do not think the bouncing is the issue.
Any thoughts? Suggestions?
