If you go to toys r us website they have the new toy book out, which may give you some ideas, and also Target has their toy book online also.
There's a really cute kitchen that my daughter got for her 2nd birthday, I can't think of the brand but it came from Toys R Us and it folds up. It was about $40 or $50, and my daughter is over 3 yrs old and STILL enjoys it. Other favorite toys - a pretend vacuum cleaner, shopping basket, cradle for her baby dolls - lots of pretend play stuff, because they really start to get into that at this age. Play doh is also a wonderful and inexpensive gift. There's all kinds of new playdoh things out nowadays and even a cool lapdesk. My daughter also got a piano with microphone that she really enjoys. If your girls like to sing and dance, I highly recommend the Laurie Berkner Band dvd. The songs are sooo cute and my daughter really really loves it!
