You need to do what you need to do to keep your baby safe.
I have read that quite a few people on here have collars on their little ones.
I don't know much about them but I have heard of breakawy collars. Also, maybe you could take her collar off when you are not home (?) Just some alternatives.
I only pretty much use collars when we are out in a crowd kinda thing. You shouldn't feel bad for wanting to keep your babies safe.
