Get yourself a carrier of some kind, she may also sleep longer in a carrier and you can get things done.
The first few weeks are trying, was it work that kept you busy in the past?
This is the perfect age to get out and about, they love it usually. Catch up with friends for coffee, meet your DH for lunch.
Go to a movie, I went when DD was this age, it was great!!
One thing I had which was a life saver for this age, was a play gym, the one they lay the under. All my kids loved lying and playing with the one we had, it would keep them entertained for quite a long time, quite a few times, I would get busy and then think "mmmm it's quiet"? I would go and check on them and they were alseep!

Soon you will find yourself with not enough time and wonder where the day has gone.
