My ds didnt crawl till 10.5 months, never rolled over without help and despised tummy time with a passion. He didnt walk till 16 months. He was happy getting around however he chose.

He is now the most active, talkative little man going around. He can read his name and can even speak some Spanish (thanks Dora)

I was worried too, but as long as you do ehat you can to encourage and teach your little one, you're on a winner!
