You're at 38+ weeks so the baby's lungs should be mature. I can't think of anything else that could be a problem, that wouldn't still be a problem at 40 weeks. You haven't had any indications from u/s's or tests that say there is a potential problem have you? If not, then I wouldn't worry about it. You're going to do fine and baby will be healthy and happy to be in your arms. With everything scheduled and all the childcare etc... taken care of, sounds like things are set. It would be if I couldn't find childcare and had an upcoming induction/c-section that I would be most stressed out. Try to be positive and enjoy the fact that sometime tomorrow your little one is going to be out in the world. You will know for sure what he/she is and can enjoy this time as a new family.
