Having two (or more) children’s birthdays around the same time can be tricky when party planning… especially with a brother and sister. Instead of throwing two different parties on different days, a joint birthday party will do the trick! Colorful invitations and napkins are perfect for a brother and sister duo, don’t you think? Make some fun music instruments for entertainment and don’t forget the confetti cake! I think both kids will be happy campers when the day is done.
