As long as you have chosen the correct size for your baby, there should not be any excess material bunching up near your baby's face. Our sleep suits are most effective if you choose the size that will give your baby a snug fit in the arms.Please check your baby's arm span measurement on our SIZE GUIDE to make sure the fit is right. If there is excess material bunching up near your baby's face it is likely a sizing issue. We recommend you wait until they grow into it before they start wearing it again.
