Thanks Playfelt. I am also going to talk to the parents about how/if they are dealing with this behaviour at home. My husband said he saw her take off down the road one day when the dad was taking her to the car, so I am certain I am not the only one experiencing this problem. She definitely doesn't seem concerned about getting in trouble...most kids this age would at least pause and think about it when spoken to sharply...not this one! The problem occurs mainly when we are moving from downstairs to up and when we are outside, so I will keep her glued to me at those times as those are the times when she could actually get into serious trouble. Playfelt, you are exactly right...I find the kids who start with me as babies normally go through this phase between 14-18 months or so, but they are not very fast and easy to catch and strap into the stroller. This little one is 2 and extremely fast, so it is much much more scary!
