Our daughters would probably be great friends. Mine also has two imaginary friends, one she calls "the man" and the other is "the spider". She also spent all day as baby swiper and told me I had to be mama swiper. I spent a lot of time today yelling, "OH MAN!" when she told me to stop swiping...
There's one thing she LOVES a whole bunch and that's tents. She'd probably go ape over a wooden playhouse but we don't have the cash yet to buy one of those prebuilt playhouses for the backyard so she has two mini tents that she plays house in. They fold up which is great. One is a disny princess tent with windows and roll up doors and the other is a little bug tent with a skylight and she brings her toys in there and plays and the cats get in there and she plays with them.
She adores little boxes that have latches that she can put things in. She has a bunch of little plastic animals she calls her "puppies" that she organizes into little $3 wooden boxes that I picked up at Michael's craft store. I bought a bag of sparkly fake gems for about $3 but didn't let her see them. I told her if she left her treasure boxes out on the kitchen table, tinkerbell would come and decorate them for her. After she went to bed I bedazzled the boxes with the help of a little gel superglue and she adores them.
She loves collecting polished rocks so I pick a few up every now and then from this toy store that has a bin of them and give them to her to put in her treasure boxes.
She likes foam swords. And hats with feathers in them. She doesn't have a play kitchen but she has a shopping cart and a bunch of play food. She doesn't play with the plastic food at all but she loves the shopping cart. She has a bunch of stuffed birds that tweet when you squeeze them and she loads the car up with them and takes them for a walk.
She loves stuff that lights up in the dark. Glow sticks, magic tinkerbell wands, flashlights etc.
