I'm not used to this. Jaxon NEVER attempted to climb ANYTHING. He's not too fond of heights, and I never realized how fortunate I was for that.
The highchair was in that spot because I had just given Jax a hair cut. DH took him upstairs for a quick shower to rinse off the hair and he left Abby down with me. I was vacuuming when I looked up and saw her sitting in the highchair. I was quit perplexed because she had just been tangled around my legs helping me to vacuum. And I clearly still heard the shower running upstairs. So, I shut off the vacuum to go upstairs and inquire whether DH came down and put her in the highchair. He hadn't. I came back downstairs, got my camera, took her out of the highchair and told her to do it again.
