My 15mo DS crawled (late-ish) for yonks. He then progressed to... "walking on his knees", kinda like an upright crawl. He'll do 4-5 proper steps (max) but then drops back to the knees. I haven't been too fussed, I figure he'll get up when he's ready. My nephew was a bottom-scooter and didn't walk till 19mths.

But, in the last few days a few people have questioned it. My FDC carer commented that she's never seen it in 20 years. A random stranger at the pool informed me that he MUST see a chiro as his brain won't develop properly (gee thanks!).

So... it's just got me wondering if others have done it, and if anyone else thinks it would be cause for concern?
