When my DD turned 1, I just did an immediate family party. I did an afternoon thing coffee and cake after her nap and that was that. I had made her this ridiculous princess castle cake - Honestly they don't remember anything. Just the 4 of you will be just fine
Do a cook out at home or at a park. Kids play in the water and have a cake smash for her. Then she can play in the water afterwards.lol. My daughter will be 1 Sep 4th. Close friends and family. I rented our town community building. Nice and air conditioned.
For my dd first bday I started a tradition that to this day continous with both. I wake them up with ballons in there room and bed. It all stated on my oldest dd first bday I rememberd how pretty my room looked at the hospital with ballons and I decided to do that again for her exept this time she could play with them so I used air blown ballons in her crib too. The rest of the day was just the 3 of us and a small cake ;)
