Daddy work, mom stay!

I had a difficult time leaving for work this morning.  Usually my Lil boy is still asleep when I leave home but he was up and awake this morning.  When I told him that,  mommy's going to work and he said "daddy work, mom stay" and he mumbles  then said it again several times "daddy work,  mom stay"

His dad used to say to him "daddy go to work" and he remembers that. Daddy was gone all day but I stayed home with him, now it's all different. He hasn't seen his dad for over 2 months and now I'm saying "mommy go to work" he didn't like that.  Poor baby, my heart hurts and I felt bad leaving him today.
