I think the blocky wooden furniture is Plan Toys. Not sure about the baby stuff.
These are Barbie things that came with a house I did not want. The sweet Girl Scouts sold the accessories to me separately. I was ready to buy the house, too, and just let them keep it, but they were easy. All this will work well with 1:12, I think. I especially love the tall green tropical drinks and will have to use them right away. Roll of pink toilet paper is just too much.
