We've gone through this with Jaxon too. Today my hubbie was watering some plants outside and Jaxon was on the front step. He doesn't go down the stairs (yet) so normally we don't have to worry. Jaxon was watching a bee or bird or something and ended up falling down the stairs. Hubbie tried to grab him and he took off around the back. He spent about 10 minutes chasing after him as well. Not fun.
I'm hoping this is something he'll outgrow - I keep joking that he's in his teenager phase (7.5 months).
