Jack still isn't walking.
He is making huge strides (heh) with his "cruising", and even scoots around on the floor now and again. You should also know that he's never crawled. Common enough, I've learned, for kids who were intubated and on oxygen as long as he was.
Most importantly though, he is now totally just "one of the kids" and interacts with everyone like any other 16 month old. He even antagonizes his siblings whenever possible, which shows that he really is one of our kids. He pulls hair, grabs, and shrieks with the best of them. In fact, I am certain I suffer from a shattered eardrum, courtesy of me not getting to the sippy cup quickly enough.
Well-behaved children make me think "hospital switch." My kids are all definitely from the same gene pool. A little shallow, yeah, but with the good toys.
