J.S.
Hi J., I am a mother of six, and I have grandchildren. It may seem easier to let your baby sleep in his carseat, and he may sleep better, but it is a hazzard. It has been proven that babies can move and get tangled in the straps, or if they are strapped in, they have pressure on their little chests. In a class I took on "safe sleep" it talked a lot about Sudden Infant Death syndrome. and they talked about the dangers of babies actually dying in their car seats, or carriers. Sudden infant death syndrome is a threat until your baby reaches one year old. but the risk is higher before six months old. We do not know the exact causes of Sids, but we can eliminate the risk factors. I really do not want to scare you, but it is in fact a fear of today. I would try to let your baby lie in his bed more often during the day. and spend less and less time in his seat. and try propping him up (by propping up the whole matress, not by putting blankets in the crib.) try putting him in his bed when he is so so tired, but still awake. let me know if you have any luck. here anyone can read up on SIDS http://www.nichd.nih.gov/SIDS
