So both my DDs have December birthdays, 2 weeks apart. DD1 is turning 3 and DD2 is turning 1. I've asked DD1 a few times whether she will share her birthday party with DD2. She sometimes says yes, sometimes no, and then it seems like as long as they get separate cakes she's fine. The party would cater 99% to her anyway!

It's just going to be at my parents house and only inviting family really and maaaybe a few close friends.

Feel a little guilty to not have a separate one for DD2, but obviously I don't feel THAT bad to insist on separate parties. I don't mind doing 2 since both will be simple more or less, but clearly it's easier to combine as well. Thoughts?
