What happens to baby snakes once the mother delivers them?

Well this depends entirely on the breed of snake you're asking about. Some snakes, such as garter snakes, will give birth to live young. Others, like (my personal favorite) the Western Hognose, lay eggs. Most egg-laying snakes are fairly uninterested in their clutches and will abandon them shortly after they lay them. Others, such as the king cobra and some species pythons, will stay in the vicinity of the eggs until they hatch. Either way, the mothers leave after the eggs hatch. The vast majority of neonates hatch from their eggs by using a temporary "egg tooth" located on the end of their snout. This "tooth" looks more like a little mini-unicorn horn. They use it to slice open the egg. Now, I'm not sure how it works for all species after this point, but the Western Hognose babies will stay in the broken eggshell for about two days. Once the umbilical cord has dried and fallen off, the snake is ready to leave it's shell. Forcing the snake out of his/her shell before this time can result in death by dehydration or exsanguination. :[ But anyway, no matter how our babies started, we now have live young who are not being looked after by mom. At this time they're on their own to forage for food and grow up. I hope this actually answered your question, since I feel like I threw a bit too much information at you. But there it is.
