How it should fit

  • Sleepwear should fit snugly. A close fit is safer and stays put through the night.
  • Pajamas and sleepers run true to size. Size to your child's current height and weight.

How to measure

  • Height. Lay your child flat and measure from the top of the head to the heel.
  • Weight. Use their most recent weight from a check-up or home scale.
