I have two daughters, who's birthdays are within 2 weeks of one another. It's my youngest 1st birthday and I would like to throw a little party for her however I can't do one without the other! So I was thinking of doing a joint one! Luckily they are both girls so it's easy to do a theme, but does anybody think this is a good idea? And what can I do for a joint party that's going to please both of them?
