Mae took the fire truck for a spin for the first time yesterday. My parents got this for Arlo when he was about a year old, and he didn't stop playing with it until he was at least three. In fact, he still hasn't completely stopped playing with it--especially now that Macy is showing an interest.
At this point, she's not actually pushing herself along or riding it, per se... but she really enjoyed sitting on it and bouncing. And I'm sure she'll be walking along behind it sooner than we can imagine. She has just entered the age when all she wants to do is be walked around the house, so she can practice her mad skills.
She is only nine months old (today!) but seems to be right on schedule for walking at ten months, just like Arlo did. God help us.
