They climb on everything.
When signs are posted that clearly prohibit "no climbing" that makes them want to climb more. Their eyes light up, looking at me like, "Mom...can we, can we, can we?"
I let them get some climbing in this weekend, they climbed on everything in sight and did monkey bars too, which was fitting for the two of them.
{When we're at the Zoo and watch the Chimps eat I think to myself, "I could totally see my kids eating peanut butter off each others heads. I draw the line at flinging poo at each other though, that's just wrong.}
Look at that determination...
I just wish I knew where they got it from...
