I have to admit, I think I enjoy building these as much as my daughters! The youngest is only 4 and needs a bit of help to assemble, but after it is built together--she loves it! Even my 11-year-old is having a blast, and it is easy for her to put together herself. They each come with a booklet and step-by-step instructions, so you never get confused. However, my youngest will just build it the way she likes, and still has fun, even if it is not "right".
We have Olivia's House, Heartlake Dog Show, Stephanie's Pet Patrol, and Olivia's Treehouse. These Lego sets are extremely easy to put together and loads of fun. While some of them can be a bit pricey, they are worth it. In fact, I just ordered the Butterfly Beauty Shop, Heartlake Vet, and Mia's Puppy House!
If you have a daughter (any age!) that enjoys building things, as well as playing "dolls" or dollhouse, then this is the right toy for them!
