Cold outside, warm inside

We have a pre-Spring storm outside, but we've spent a good bit of the weekend making Endrias and Bethel's rooms warm and comfy.  We're having a problem though.  We have no idea what three and four year olds need.  We went to Toys R Us to just walk around and see what we don't have, but we came away with a couple of sippy cups and some small eating utensils and that's about it.  We did get some pretty cute bedding though and their rooms and play rooms are coming along nicely.
