Little Keeper Sleeper Boys' 100% Cotton (Size 2T-5T) Long Sleeve Footed Zip Back Inescapable Pajamas

These things have been life savers for us. Our little one has gone through phases of getting out of her jammies in bed since she was about 14 months. These are the only ones she hasn't been able to get out of. We're in our 3rd size as she grows. Each one has fit similarly to her other clothes in the same size. She finds them comfortable as well, and I like that the fabric is soft.

Overall, "Little Sleeper Keeper" offers a practical solution for night time undressing. My only fault is in sizing. I found that the pajamas run on the larger side, so one should keep this in mind when ordering. My daughter normally wears a size 2 in pajamas. I order her a 2 in the "Little Sleeper Keeper" and they ran big as you can see in my photo, despite the size chart said a size 2 fit 25 - 30 lbs. My daughter is just a tad over 30 lbs. The legs were also rather long, and my daughter is a tall girl.
