RE: Please help! We have a crawler!
Rashmi, why do you want to gate things off in this way? In a short amount of time, she will need a lot more room to play and you will need to re-configure at that time.
If I were you, I would babyproof the bookshelves, make the TV is secure and let her have the run of the area. :) If you like, get a couple of small gates so that you can block off the kitchen if you need to while cooking.
