I work FT too. Of course its possible. Things that make it work for us:
While I do all the drop offs, we share pick ups. On the rare weeks that I'm solely responsible for pu, it is VERY tiring. I literally do not have 5 minutes to myself, since I commute with DD.
My hours are fairly flexible. I can switch around from 8-4 or 10-6 if I need to, for example.
We are very happy with our daycare. Having that peace of mind makes it all possible. Really. I could not sit and concentrate at my desk if that were the case.
I don't care too much about how my house looks or serving fancy meals. Its more important to me that our time at home is fairly relaxed. Clean enough to be healthy, dirty enough to be happy is my motto!
We don't do a lot of scheduling on evenings or weekends. Too much scheduling stresses me out!
Bfing and cosleeping made my life soooo much easier, esp when DD was younger (she's 3 now).
I do work with a mum who negotiated a 40 hr week in 4 days. She has been here a long time, and yes, she does end up getting some calls at home or even coming into the building sometimes on Friday. She tells me that having that day to do the groceries, the laundry, clean the house, etc etc is worth it so that she can focus on her family the rest of the weekend. She was the first to do it here, and will probably be the last, even though she does a great job.
