We have been under the weather ~ therefore we have been stuck inside for almost an entire week!! At this point I thought anything other than our usual toys would be exciting. I grabbed these disposable 'shot glasses' thinking my little one may take a liking to stacking and sorting them. My daughter LOVED playing with these little cups. She was building, stacking, sorting, lining them up, etc. It was great fun and for TWO DOLLARS might I add. She has placed them in her toy box and requested that we play with them again first thing in the morning. Make sure you stash some little cups away for a rainy day!!
