Sitting pretty

So, at last the time has come.....my son can sit! He is still a little bit whobbly but for most part, he is sitting for a few minutes at a time before he takes the backwards spill. So what's next??? Probably crawling. I look forward to the day when he can crawl right up to me but yet, I will be patient because I know that this means he will be making me chase him more than anything.
