We've created our size guide as a frame of reference to help you figure out what size is best. Please remember that kids are unique and come in all shapes and sizes at every age!
  • All measurements in inches and taken from a relaxed garment.

Baby Sleeper

The low down on our fit: Our newest Baby Jammers sleeper pulls gently over the head and zips closed between the legs. Tapered wrists and ankles ensure a secure fit. The fit leans towards the larger size leaving your baby lots of room to grow.

Kid Jammers 

The low down on our fit: Kid Jammers are made from our ultra-soft fabric that drapes softly against the body. Our dual size system leans towards the larger size so if you find your little one between sizes, we recommend sizing down. For example, a size 3/4 fits like a generous 4.

Washing: Our Kid Jammers fabric is not pre-shrunk, this means you can expect some slight shrinkage after the first wash. Keep this in mind if you find the PJs roomy on your little when trying them on. Please note, washed garments are not eligible for returns or exchanges so make sure you are happy with the fit before you wash them. Machine wash cold and tumble dry low inside out.

Fabric Treatment & Testing: Our fabric is not treated with any flame retardant chemicals. We adhere to all children sleepwear safety guidelines.
