Babies need to sleep on their back!

This has always been something the doctors and nurses stress but I never knew it could be so serious if we don't follow it. I read somewhere that babies should not stay in their car seats for more than 20 minutes at a time. Apparently, if they are awake, it's not so bad but it could potentially lead to death if the baby sleeps in an upright position such as a car seat for a long period of time, as in the case reported over a year ago. This upright position causes breathing problems due to the lack of oxygen they can receive. In the news story that I read, the lady placed her baby to sleep in the car seat since the baby slept better in it than in the crib. This eventually led to the baby's death. I was shocked to read about it. The lesson to learn here is that babies should not be allowed to sleep in their car seats for more than 1 hour and should be checked upon several times on long trips.
