Once our girls figured out how to kick their blanket loose so they were no longer swaddled, while they were sleeping, we were told they shouldn't sleep with a blanket anymore because the blanket can be a choking/suffocation hazard.
We live in a colder region, so during the winter, we keep the thermostat turned up pretty high so that they stay warm in their crib.
When it is okay to start covering your baby with a blanket when you put them to bed? Are there some good guidelines?
