What Do I Buy For Our Daughter's 4th Birthday?

Our daughter will be going on 4 years old this September. I can't believe how fast time has gone by. It just seems to have slipped away from me. It doesn't feel that long ago that I was telling the hubby I was pregnant. I swear as the years pass and I get older time seems to move by faster. Our daughter has turned into this beautiful, intelligent, funny and all around fun little girl. It still amazes me that she is a part of me. I always wonder how I got to be so lucky to have such a beautiful child. For the first time since she was born I have no idea what to get her for her birthday. With all the new and amazing toys that are out on the market you would think that It would be an easy task. Nope, not for me. I'm at a loss. I was thinking about getting her a doll house. It's something that I always wanted as a child and never managed to get due to my mother being on a tight budget. Lately she has been enjoying the little dolls that she has received in the past, so I think the doll house would be a great idea. I was thinking about checking out etoys. I had really good luck with them last year and they offer some fantastic prices. Much cheaper than any other retailer I've come across. If anyone out there has any idea's please shoot them my way. Any suggestions are welcome.
