Grey one piece

Love this color and material! I wish the one piece came in larger sizes for my boy with special needs.

Runs really small

Hi, so I really love the style and the fabric of this item. That is 5-star. However, I purchased 6-9 month size and it’s really more like 3 months. I’m really sad because you know I paid a little more for these and my son will probably only wear the 6-9 month size twice. Just know, sizes run small.
