Monkey see, monkey do

We've been using this phrase a lot lately.  Whatever Leighton does, Riley has to do it too.  When we are eating a meal and he has a drink of water, she needs to stop eating to drink water.  When he gets up on the couch in the playroom, she needs to get up also.  When he takes off his shirt, guess what Riley wants to do right away?  Of course, she points to her shirt and tells us she wants it off.

But, the other night at dinner, she wasn't the only one being a monkey!

Let's see if you can guess who started this off and who copied?!?!
