Each toddler blanket sleeper features a zipper down the front to keep middle-of-the-night changes quick and simple. Plus, the baby sizes all have safety tabs at the top of the zipper to prevent their sweet faces from being poked and irritated (safety tab not included on toddler sizes). These snuggly baby and toddler sleepers are designed with fun prints and colors to add a little excitement to sleepy time. Each blanket sleeper is machine washable and dryable. We had our essentials independently certified with STANDARD 100 by OEKO-TEX so that you dont have to worry about harmful substances in your babys nursery.
