No, you don’t have to invite every child just because you went to their parties. You really don’t want to overwhelm your baby especially on the first party. Invite kids that your child plays with and has fun with, I also invite their parents. Alex is still pretty young and I couldn’t handle a party and a lot of kids with just me and Lucas, other parents are great because it is another set of eyes. I still stick to close family and friends when it comes to birthday parties.
