My question is, is a bouncy seat (semi-reclined) as dangerous as a car seat? I wear DD a great deal, but there are times when it's useful to be able to put her down. She is much more likely to stay asleep if I put her in her bouncy seat than on a flat surface -- she nearly always wakes up immediately if I lay her on a bed or cradle. (No difference swaddled or unswaddled, either.)
I know it's very dangerous to let a baby's head fall forward onto her chest. But if we assume that I can see the baby at all times and her chin is NOT resting forward on her chest, does that mean all is well in the bouncy seat? Or do baby's oxygen levels drop in bouncy seats, too, so that allowing a baby to nap in one, say, once a day, could increase the risk of things mentioned in the article above: ADHD, decreased IQ, delayed motor development, and impaired attention?
