I had a water party for my first. She was a July baby - so sprinkler pool, we had a family BBQ, she had her smash cake and it was super simple but fun. We did something similar for our twins, but indoors since they are December babies.
My son turned 6mnths yesterday and this is the question I've been asking ! Lol
I think just a home party is fine or as my sister is thinking of getting a room kind of like a hotel ballroom. Nothing too big but enough and decorated with nice decor. 🙌🏾
