I’ve been told mixed things about the car seat inserts on wether they are safe for newborns. I feel like my baby needs more support in his car seat because his head is always to one side and I’m not sure if that’s comfortable or even safe for him. Here is what I’m looking to add In on my car seat and how my baby looks in his car seat without the inserts. I’m a ftm and just want to make sure my little bean is safe and comfortable.
