I went bak to work 4 weeks ago, leaving my ds (now 7 1/2 months) with a child minder.
The first day was hard - is was so strange riving with no little person sitting in the carseat. But like FJ, as soon as I got back, it was so great to see everyone, and get stuck into something that wasn't about babies, the day flew by.
That night I drove home like a maniac, was gutted to find ds had already gone to bed, and spent a long time sitting in his room staring at him sleeping.
Since then though, I havne't looked back - ds loves the change of scene and different experiences he gets with the childminder and is always smiley and calm when I collect him. I feel SO much happier, having a bit of balance in life. I love the banter at work, the chance to feel like an individual again, not just 'Littlejay's Mum', to feel under pressure again, in a different way than at home, to be able to have proper adult opinions on things, and mostly, a bit of adult company away from ds for a bit.
I think I value the time I spend with him more now ( I only work 3 days, so I still get plenty) and make an effort to do fun things with him.
Good luck - I'm sure it won't be as bad as it seems now!!
