Our daughter never really "played with Barbies" as much as put on "fashion shows" with her barbies.
This was before digital cameras were small enough for her to handle.. so we have a ton of photos she took using "box cameras".. Now you could take the photos with your phone on put them online for her to organize into a show.
Our daughter had tons of Kens and Barbies along with all of the clothing.. She would mix and match and make Barbie clothes out of pieces of fabric , ribbons, saran wrap, cardboard.. etc,, then pose them and line them up on shelves, book cases, the back of the sofa.. front steps.. It was pretty amazing and clever what she would come up with.. Then I would set them up and she would decide what was the prettiest, funniest, ugliest.. etc. She would make little awards or sashes for them..
Our daughter was never fond of baby dolls, but loved her stuffed animals and would use them to pretend she was a doctor or the vet and needed to care for them in the "hospital".
Or we would play toy store and I would buy toys and she would ring them up on her cash register (I was in retail, so she knew all about selling). She would have a sale on all of the Barbies.. and try to get me to buy them..
She did play alone a bit, but since my husband and I worked full time, we liked playing with her and spending time with her whenever we could.
Puzzles, blocks, games. She was always drawing, so we all spent a lot of time drawing, cutting, pasting.. etc.
Outside she loved her "Air pogo" and her "Twizzler" Both of them hung from the tree out front. She spent hours on them.
We also used our driveway with sidewalk chalk to make roads, parking spaces, traffic signs and destinations, so she could drive her trike or car around the road. I would be the Police directing "traffic". The we would trade places and I would walk along the "road" and she was directing me.
We would build tents inside with all of the sheets, pillows and blankets.. It was epic..
Enjoy this time with her. She will soon be a teen and you will miss her imagination and innocent ideas and spirit.
Our daughter is now 21 in college and still talks about how she loved the way we all played together. She says her friends up at school are jealous when she tells them about the crazy things we did (and do ) as a family.. Their parents apparently did not play with them.. Our daughter was surprised because we and all of our neighbors played with our kids quite a bit.
