Has anyone had trouble with their infant fighting their car seat? This is our first child and I am completely out of ideas and don't know what to do. She fought the infant seat and now is fighting the forward facing seat. No matter how tight or how loose the belt is she bows her chest out and holds her breath. She does this over and over until she is completely worn out or falls asleep. I had high hopes of this getting better in the forward facing seat, but she is 14 mos old now and I don't see it getting any better. Any advice on why she is doing this?
