Gift for a new mom?

My SIL just had a baby girl last night! Of course I will be spoiling my niece rotten, but I also would like to get something for my SIL. Any ideas?

Thanks!!!

What I have done for my friends:

I have cooked a couple of dinners and delievered them to her so she didn't have to worry about cooking for the first couple of days

Another friend got gift certificates for me to baby sit for her daughter

Another friend we gave her a g/c for a manicure and pedicure.
