California
We haven’t been there, but we went to our local fair! I know it’s different, but we brought a little cooler with milk, and snacks. A carrier, a hip carrier, and the stroller in case they want to be held! Also if you have a wipeable travel changing pad, then you don’t have to find a bathroom every time you need to change them!
I recently visited Disney California Adventure Park and it was very baby friendly! Definitely recommend even if they can't walk, there's lots of rides the babies can get on. My baby was 10 months durning that time and we had a blast. Also we got the lightning pass which made it easier for the rides with a height requirement. Very fun!
We took ours at 4 months and had a great time! She loved the rides she could go on. They have a mothers/baby lounge in both parks that is nice if you have to nurse or pump. Definitely bring a lot of snacks. And look into rider swap!
