Hey Natalia,
I have a 2 year old daughter, so I understand where you are coming from they are at a hard age to buy for. My daughter is very into baby dolls, books and anything girlie she loves. We got her the disney princess kitchen set at Aldis, it is musical and 1/2 the price of ones at toys r us. We also got her accessories to go with the kitchen, a new baby doll stroller, a set of triplet baby dolls, some books, princess dress up set, 2 books for her baby leap pad(the baby leap pad is great helps them learn alot of new things), we also bought her a vaccumm, but stocking stuffers are more difficult. They have to be smaller so we got her a little kit of baby doll accessories, i was thinking of also getting her crayons and a coloring book, and a few of her favorite snacks. Well ok these are things i think are great for little girls but every child is different, every mothers opinion is different and it also depends on how much money you want to spend. Good luck and if you'd like to talk to me more feel free to email me at ____@____.com. Happy Holidays~M.
