I know how you feel; it’s so hard not getting to see much of your baby.  It is in a way comforting to know that it’s harder on you than it is on her, but also a bit depressing iykwim.

My DD was only 5mo when I went back to work fulltime.  A few things really helped me.

• Setting aside time in the weekend just for her and I.  Initially we’d just go for a walk (me walking, her in the stroller) and play at the park, when she was 1yo I enrolled her into Saturday morning gymbaroo, then when she was 2 ˝ we dropped gymbaroo and she started dance classes.
• Doing something just for me at lunch time eg. lunch with my girlfriends every fortnight, exercise, quiet time with a good book, toddler free clothes shopping, meet DH for lunch – whatever tickles your fancy really.
• Remember that you are setting her such a good example.  Rather than doing what you want to do you are putting your family first and going back to work fulltime because that is what your family needs you to do right now.  Think of it as a selfless act which shows what a great mummy you are.
• Have something to look forward to.  It may be a family holiday or a new car.  For me it was having another baby and the knowledge that I would be taking longer off on maternity leave the next time.

Good luck with your return to fulltime work.
