My little Ryan turned 1 on June 25th. He's not walking yet either, but cruises like crazy and can climb just about anything - today he somehow managed to get up onto a chair in my living room. He also LOVES climbing up and down stairs - luckily he's quite safe about coming down backwards.
He'll happily walk holding my fingers or even just one hand, but as soon as I let go, he plops down onto his bum. My twins were early walkers - 10 months for both of them - so it's strange for me to have a 12 month baby with no interest in walking. I'm in no rush, though - he manages to get into enough trouble crawling, I can't imagine how much trouble he'll get into when he walks!
