I bought this suit for Evelyn the day we found out we were having a girl. It was on sale at Janie & Jack; the matching swim cap, too. Knowing she would be six months old on May 21st, I got a size 6-12 months.
Turns out it's a little snug, and short. It might get us through June, but I went ahead and ordered a new suit - size 12-18 months - to wear the rest of the summer.
Sam and I put the pool on the front patio and filled the bottom with just a tiny bit of water. We dipped Evelyn's toesies in, and she screamed. And screamed. And screamed. So we decided to dump out the water, put her in the Bumbo, and give her lots of toys to play with. She ended up having a great time, but what we're going to do when Sam wants to go to the big pool I don't know!
