My birthday dinner from my mommy..

You need to find a way to stop him ... Or cover is leg right there very good ..:: contact The company that made it and inform them I was happening to your Child leg let them know that the babies moon and they shouldn't have item that hurts them like this

could the car seat be too hot? could be an accidental burn I can't see it too well. try an ointment and try to protect his legs while in the car seat!

Wrap them while he is in the car seat to prevent further irritation but definitely don't keep them continually wrapped..this will cause infection. It needs air to heal, you can also put a little skin cream on it but don't keep that on their constantly!
