How long did you wait to go back to work after having a baby?

My work has got a new Service Manager so i have a new boss, she tried to ring this afternoon and she left a message asking me to call her back.

DP had to call her for some reason and she asked him when i would be looking at returning to work.

He's saying i could in a months time but i'm not sure if i'll be ready.

I wont be full time or anything only doing 1-2 shifts a week.

P.S i work for dan murphys.
