DD1, and 2 of my nephews (turning 5 and 4) have birthdays this month. We are planning on having a small get together for their birthday (12 people at most there). The problem is, DSD also has a birthday this month (turning 12). She will be at the get together, DH will not. Should I make an effort to include her birthday in this? We are doing themes for the smaller kids with cupcakes and goody bags, etc and I'm not sure at what point I include/exclude her. I'm trying to not make this about bio versus step but the age difference is throwing me off here. Regardless of whether she gets themed cupcakes and a goody bag, she is getting a decent amount of money in a card. Suggestions?
