Sure enough, when we were in Louisville for Labor Day, she stood up in the crib in an act of protest against taking a nap. (BTW, that was my crib when I was a baby.)That night, she did it in her own crib too, and we promptly lowered the mattress to the very lowest level. It's practically to the floor, and that is where it will remain when it becomes a toddler bed, until she's ready to move to a "big girl bed"!
Nonetheless, she can still peer over the edge, and may one day learn to crawl out!
She is now able to cruise around the coffee table, pulling up with greater and greater ease and slowly taking careful steps as she hangs on to the table or the couch. She's so determined--grunting and huffing and puffing when she can't seem to summit a particular mountain. She's a go-getter, and we're so proud of our girl!
