I was still recovering when we left the house with Abby for the first time. I couldn't bend down completely to get Abby out of her car seat so we placed it a few stairs up on a landing inside the house. We went about our day until we heard an awful crash followed by Dylan crying.
He was curious about her car seat (his old carseat) and had tried to sit in it. When he was done with that adventure he went to get out but it tipped forward with him in it and he came crashing down the 2 stairs, hitting his head on the hardwood floor (see picture of forehead bump!). The car seat landed on top of him.
This falls into the lessons learned category. We keep her car seat in the coat closet now :-P
