Dilema.. how will I keep up with my workouts..

Options
So, I have to get a job.. I am a stay at home with 3 children at home... I currently work out every day.. then get ready.. get my kids ready, take my 5 year old to school come home get some laundry and dishes done, while my 2 boys take naps.. pick my little girl up at school come home, start dinner, or finish dishes and or laundry... But now with getting a job I am going to work at night from 10:00 pm to 2:30 am.. My youngest is ONLY 4 1/2 months old.. so sometimes I will have to get up with him when I get home from work.. he ususally stays asleep most of the night but sometimes he wakes up.. my boys wake up about 6 or 6:30am.. so that would be like 3 to 3 1/2 hours of sleep.. where am I going to get the energy to workout every day.. I WANT to keep up with working out every day..but is it possible?? any suggestions?
