When should I switch from a regular carseat to one of those ones where they like sit up? I think they are called convertible carseats. My baby is about 4 and a half months and I have noticed that some girls that have babies about a month older than mine have said they already have one and have had it for about a half a month or so. I'm not sure if they use it or the regular one but I have just seen pics of their baby in it.
It just seems like more hassle to Me to switch because then I don't have anything to carry baby in and I just have to carry her in my arms since she doesn't sit up or anything yet. Am I missing something?
