DD1 (2.5) has started climbing everywhere - moves chairs, reaches up and puts stuff in microwave (no turned off at the wall). Climbs from windowsill to desk to high shelves to get photo album. Scales the heights of the tall bookcase to get stuff from the top shelf, climbs on top of toilet cistern to get to medicine cabinet. This mostly happens when I'm trying to feed or deal with DD2 (11 months). I just don't know what she's going to do next and I think she might really hurt herself. Any advice gratefully received.
