How do you handle having siblings with the same birth month?

My first is Dec 11, second had to come early and has a Dec 28th birthday. Aside from the fact that we also celebrate Christmas and Hanukah, we’ve made December an incredibly busy month. Wwyd to celebrate both individually and also celebrate with family? I was just thinking of doing a birthday party for my toddler this year then was like.. how would we do 2 back to back, one being right after Christmas. Lol ugh
