I’ve noticed MDF babbling more over the past week. She’ll normally just babble to herself, and not necessarily to anyone else. When she does respond to others it’s by saying “hmmm!” in a questioning tone (to get a better idea see the expression below).
When the stroller was inside, CDF was helping her push it up and down the hall. She tries to reach the handles we use, but has to settle with grabbing on to the basket at the bottom and pushing there. She’s quite good at going up and down the hallway, but she can’t turn it like she can with her other walker toy.
