My baby doesn't like a blanket while sleeping, but am afraid that she will catch a cold. Should I make her wear socks?

Hey it's actually safer to not put a blanket on your baby while sleeping, as it can lead to suffocation and increase the risk of SIDS. If you're switching on the AC or if the weather is cool, make her wear comfortable night clothes with full sleeves and legs, as well as comfortable socks, so that she is warm even without a blanket. In winter months, you can make her wear thermals to keep her warm at bedtime :)
