I have a jumper too; when he was a few wks old he could scale the tallest baby gate we could find
and now can jump on any kitchen counter
. The counters, top of fridge, shelves, and bookcases are not safe! People always ask why everything is so bare and plain in our home, but gotta keep it Ranger proof.
I'll have to get a video of him jumping on the counter, he does it with such grace it's sickening!!
