Yesterday Charli was playing in the lounge room while Paige was with me in the dining room doing her spelling words (which is a story all of it's own) when she suddenly started crying. She came running in with a blood nose. When we finally got her to calm down and tell us what happened, we discovered that she had put her little wooden chairs on top of the couch and then when she climbed on them she slipped and banged her nose.
About 20 mins later after her nose had stopped bleeding, the boy went into the lounge room to find Charli with both of the wooden chairs on the couch and she was laying on top of them.
Apparently a bloody nose was not enough of a lesson to stop her from doing it again.
