I don't read parenting books, so I have no idea what all the "milestones" for babies are. And I have no idea when they are supposed to occur.
This has its pros and cons - the biggest pro being that I get excited about everything Bjorn does that is new and different from the day before. I'm not searching for the next written "milestone" and I don't get worried that he hasn't sprouted a tooth/crawled away/spoke in complete sentences yet.
Today's Mama Loves Milestone:
He can sit up. All by himself.
Of course, it is only for about a minute, and then he slowly weeble-wobbles and topples to the floor.
Then we all laugh, sit him upright again and do it all over again.
Yes, I laugh when my baby boy falls over. But he's very durable. He can handle it.
