Standing But Not Crawling???

Mummy's amazed that I appear to have skipped the crawling stage. Mummy's been trying to train me to crawl for a while now, by trying to stir my interest by putting stuff in front of me. I just try to reach out as far as I can, or flip from side to side until I reach it, yet still not crawling. Sigh... Mummy's giving up. But she then realised I keep wanting to stand up. Now, as long as I grab onto something, I will stand up. Check out these photos. I just learnt to stand up on the sofa...
