indoor activities/toys for 16-20 month old

so its finally starting to sink in that winter is coming, and I realized I need to buy some things to keep DD form tearing apart the house this winter.
on my list:
crayons
puzzles

and..thats where it ends. looking for some recommendations for toys/activites to keep DD busy. shes 15 months now.

Re: indoor activities/toys for 16-20 month old

i am thinking the same way-and DD doesn't have a whole lot of indoor toys so we are getting her a few things that i am hoping will keep us occupied if we get snowed in etc.... for Christmas she is getting a play kitchen, pop up tent, play tunnel, fold and store slide, magna doodle, big blocks, bowling set and a few other smaller things including books which she loves. puzzles too, some little people sets and a doll carriage. DD will be 18 months by Christmas.
