Oh, I so can sympathize with your position, for we also have a dd almost 2 (on 12/20) and she is the youngest of 4 - we literally could stock a toy store in our home

And with dd's birthday just days before Christmas, we also had to shop for birthday gifts!
We are helped by our Christmas gift rules...only 3 gifts per kid (plus stocking stuff) and we do not do Santa. At least having a specific number of items to shop for helped a bit. We also do 3 gifts for birthday. However, everyone was asking what to buy for dd and that has been a challenge.
We have bought dd some things we have had before, but they were pretty beat up or we thought it would be nice for her to have her own. Does your dd have an area of play that particularly appeals to her? Our dd is crazy for baby dolls, so one of her gifts is all new doll stuff just for her...baby crib, doll, stroller. Yes, we have this stuff is some form for her big sister, but I know dd will be thrilled to have her own stuff.
We also bought dd a fabulous princess trike from ToysRus...it is super cute with a canopy, water bottle holders, push handle for the parents, etc. Another gift she is getting is a ball pit...we have actually never had one and I think she will enjoy this a great deal this winter.
Younger dd is also crazy for the princesses thanks to big sis, so we bought her all of those soft, stuffed princess dolls they have at The
Disney Store. DD just loved them in the store. They are cute and I know she will play with them like crazy.
We also like to have a special jewelry piece for each girl at christmas...we started a tradition of buying a pearl (her birthstone) for older dd that is on a gold chain, and we add a pearl each Christmas. Younger dd is getting a charm bracelet for Chritmas that we will add to over the years (great design from a local jeweler where you can actually add links to the bracelet...so dd can wear it now, but we can enlarge as she grows).
My sil is buying dd one of those aqua doodle mats that allows for writing and coloring with water, and I thought that was a super idea as well.
Hope you are able to find some things that will make Christmas special for your dd and memorable for mom and dad
