Outfit your baby lightly, particularly during hot days, to make air flow better. As for apparel choices, leave some breathing room for the stump. Kimono-style tee shirts work best to let a little bit of air in. There are, however, onesies that have stomach button holes in them. Once you get your baby residence, it would certainly be best for the umbilical stump to be laid off. To do this, make sure that the baby's baby diaper is not touching the location of the stump; or else, the baby diaper can draw on the stump as well as possibly harm it.
