I have a stool I let R and G stand upon when I am preparing non-hazardous/messy parts of dinner so they can watch and learn.
G has watched R and I use the microwave to prepare our microwave popcorn many times. I just didn't realize how much he had learned...
In goes the sippy cup:
A quick door close,
a few buttons to push,
and voila, microwave action!
Needless to say, G was very, very proud of himself and I put the stool away for the day.
Life is sweet,
