It seems a bit early to be asking this, but I make everything by hand, so I usually work on both Christmas and birthdays during the year in advance.
My daughter will be turning 5 at her next birthday and her little brother will be turning 1. Their birthdays are three days apart. How do you handle different age/different sex kids' birthdays when there is an age difference? I know my son will only be one, but after this year, they'll probably have different friends, etc. Everyone tells me to just give them one party together but I feel like I'd be cheating each out of their special day and I also feel odd inviting friends who will probably feel as if they have to bring two presents to the party (one for each child) instead of just one. On the other hand, I'd feel strange inviting people to two different parties or just inviting them to one and having them wonder why they didn't get invited to both.
How do/would you mamas of many with close/same birthdays do it? And what about decorations? Do you just do unisex decor at the parties?
