You must buy the ottoman too! My gift to myself and my friends and family who gave me Babies r us gift cards, was a Shermag glider and ottoman from BrU. It would not have been as comfortable to nurse without that gliding ottoman. I wish it had a steeper recline because I probably fell asleep in it with my mouth hanging open....haha. but what ever you decide to do, make sure it coordinates with her other furniture, like wood color (mine is cherry to match MY bedroom furniture, where it is now), and fabric. All of that is personal taste since it will last her for years and years until it gets handed down or borrowed out. I hope she didn't pick the most expenisve one to keep up with the Jones's, if you know what I'm saying. I fell in love with a Dutailier, for comfort, but it didn't match my decor and it was alot more money. I don't know which one she selected, but I'd hope that she shopped around and tried them all out, at least at Babies r Us or Lazars Furniture, they are all lined up and ready for the testing!
If you can't buy the one she wants, get her a gift card to apply towards it and if it's that much money, let her pay the difference. It's not a bad thing, it's just reasonable.
Hope this helps!
