When I am cooking dinner my toddler is ready to play. Unfortunately she like her dad and brother have incredibly long limbs and can grab at things and it's simply not safe some nights to have her walking about. So I make little activities for her to do in her boster chair. This is our recent favorite.
Using an old pepper container and straws cut to fit inside she slips them through the little holes until the are all in.
I come and dump them back out ... and repeat.
She loves it, she is safe from cooking dangers and she is working on fine motor and hand eye coordination skills too!
