Ya we've all been there...what do you do with the littles when it's too cold to go outside? Here's a good one...
Just grab your biggest container and put fresh snow in the sink. I happen to have those tubs you use for washing dishes (I have no idea what they are called..they remind me of camping LOL) and I filled it with snow. Just add clean sand toys and TADA! Hours of fun.....okay...maybe the snow melts after hours but that's a lesson in science right there. Plus you know you had to clean the floor anyways and now you have little helpers to tidy up.
Go! Run outside and grab some snow and then make a cup of tea and enjoy the peace...well..maybe it's noisy but you don't have to be hovering to deal with this one!
