Baby's first birthday

Hello mommies and daddies! My son is turning 1 this August, and I'm so stressed out in planning for his party, idk if I'm going to throw off a big party or maybe just the family. Idk where to start, Idk what to buy. I need some advice please. His christening would be on the same day... If you could give me a check list, that would be delightful! #1stimemom #firstbaby #advicepls #BabyBoy
