My baby has a really chunky neck. Can I customise the Woombie neck width?

Absolutely. Unzip the top zipper 1 inch so the puller rests at the base of the chin flap. This opens the “neck hole” 2 inches.

Remember that the Woombie neckline sits high by design, so that it helps keep hands inside the swaddle and gives secure upper body swaddle effect.
