Finally going back to work... Happy, but feeling torn.

Tomorrow I start back at work. Luckily little Missy has an aunt who will be nannying her while I'm at work. Even though its a full time schedule it's only three days a week, so I shouldn't worry right?! But how am I going to make it 13 hours without boo boos hugs and laugh. By the time I go to work and get home she will be asleep. Here's to hoping we can all adjust. Any advice to keep my family sane?
