Crawling. He's just not in to it.
My son just does not seem to want to crawl at all. I've tried to stimulate him by placing his favorite toys nearby, got down on all fours to do a demonstration, laid down in front of him with my arms out....I get a few giggles, but no scooting or movement. After a while, he'll just put his head down and either sleep or roll on his slide and babble. Does anyone have any unique strategies that I could try?
