For some reason both our kids have been very driven to climb, beyond what makes sense as being normal to me. When ds was 1&2 we just couldn't leave the room without having him up on something. Dd2.5 is the same; I guess my parenting style is to leave a chair in a room unattended for 2 minutes and expect somehow that my kid won't get on the mantle to check out the crystal votive!
(No, I didn't think, oh she'll probably shove that chair over to the table and from there wedge her foot onto the window frame...)
This, to me, is similar to the experimental/destructive "tendencies" they also exhibit.
It's not quite beyond my control but sometimes I feel like I'd have to lock the toddler in a bare room to find a moment's peace. I have not read about this extent of adventuring in my regular baby/toddler books, but maybe it's been too long since I picked one up.
Anyway, something's up!
