Going Back To Work- Again

My son is now 11 weeks old and I'm looking down at his sleeping face, wondering, how am I going to leave this little man every day? I won't be around as much to make him smile, listen to him as he starts to laugh, and watch him as he learns to roll over. Somehow I have to find the energy to teach 180 7th graders everyday in exchange for time with my baby. How do moms do it (and with little sleep)?
