Congratulations to your little guy! Since this is a first birthday and he doesn't really know what's going on and given that the weather will probably be cold, I would just plan something small and low key at home. A few party games for the older children, cake, ice cream and presents and call it a day. He won't know the difference and right after the holiday people are tired and would probably like something calm and low key. have a good one!
