Creeping towards crawling

Jonathan is so close to crawling. I keep expecting him to figure it out any minute! He’s been rocking forward from a sitting position, leaning waaaay out to reach for something, and then catching himself on his hands and kicking his feet out behind him. Once there he realizes that he’s on his tummy, which he doesn’t like, and yells in frustration. :) But sometimes, particularly in the morning and when he’s outside at the park, he’s more receptive to practicing. I’m going to be glad when he can crawl, since I think it will help him be less easily frustrated. On the other hand, crawling means I have to finish babyproofing the house!
