I believe by legal right/or fight I have the right to leave at 24 hrs even if I have to put up a battle.
I also remember when I went on the L&D tour at Upper Ches that the nurse said some pedis always want babies observed for 48 hours.
Not that I'm saying you should expect a battle or anything, just I've never heard of any legal "right" to leave at 24 hrs. If the doc thinks your baby needs more observation, he won't sign the baby out. Then you're left with the leaving "AMA" question (yes, you have a legal right to just take your baby and go at any time- leave "Against Medical Advice.")
