Just make sure to keep antibiotic ointment, like neosporin, WITHOUT the pain medication in it, on the umbilical area for a few days. Check it's vent regularly, and keep it open. The neosporin actually helps with that. Get some Rooster Booster, or Poly ViSol without iron, and put a a drop in 1/4 cup of water, and give that to it. You may also add a pinch of sugar, or honey to the vitamin water mixture. These things will help strengthen it.
