Hi,
I went back to work to a stressful and long hours but very well paid job after my DD1 was born. I hated every day I was at work and didn't feel that I was committed to my job at all, my priorities had changed completely.
My DD1 was looked after by my mum so I knew she was happy and well cared for while I was at work (leave home at 7am - return at 7pm), but I felt I was missing out on her growing up.
After 1 month of fulltime work I negotiated to work part time 2 days in the office 1 day work from home a week. This seemed the perfect solution, but the problem was that on the 2 days I wasn't working we tried to cramm so much in it was really stressful. Getting to know other mums and babies was really difficult as you would only see them once a week and couldn't form any sort of lasting friendship.
After 2 years I decided to stop working, this reduce our income by 2/3 so it wasn't a decision we took lightly, but it was the best thing I ever did. DD1 made loads of friends, I made a huge network of local friends too. She could go to a local preschool and we both chilled out, it also seemed to sort out her eating problems.
I have now had DD2 and have no plans to work until she starts school, but she is now the age DD1 was just after I returned to work and its amazing what I missed out on.
So my advice would be if you can afford to have a few years off and enjoy the time with your baby as you'll never get that time back.
