I'm not that worried but it's getting a bit frustrating now!! DS is almost 15 mths. He crawled at 9 months, been weight bearing since 14 weeks but only consistently pulling up since 12 mths. At 13.5 mths he was occasionally standing alone for 5-10 seconds. Now he won't do it at all and just crawls speedily away. He refuses to walk holding hands!
I was a very late walker myself so I guess that's a real factor. Just wondered if anyone's dc was similar- i.e. crawling for 6 months and not really making progress with walking!
