When ds was tiny I hated hated hated leaving him, cried every time I walked away from him, counted the minutes to getting home again. Now he's a toddler and shall we say, boisterous.. I quite like my days at work, they are full on 12 hour days with a 1 hour commute each way, so I don't see much of ds at all when I'm working, but I always make sure my days off count with him. I always really look forward to those days, and after I've been off for three or four days with him, I'm actually quite looking forward to going back to work and being able to eat a meal in peace or go to the loo without an audience.
I do 3 full days at work and it really suits us all. I love the fact when she's with the CM I know she's having fun, and also that I don't have to think about her meals <mean mum> but I have great fun on our days off (and I don't take work home with me).
