When can my baby climb stairs
When they show an interest in them and start to climb them. If I didn't have time to follow up behind them I just pulled them away from the stairs and sat them with some toys or blocked off the stairs with the pack 'n play or chairs. But I usually followed them up the stairs as they crawled and looked back smiling at me proud of their accomplishment, then I'd make sure they were turned with their back facing out and show them how to come back down by moving their legs back down the stairs. I wanted them to know how to do both! I had one who came down the stairs siting frontwards and it was nerve wrecking to watch. Well, it's always nerve wrecking when they are starting to use the stairs.
My friends with kids his age looked at me like I was crazy. He never once fell though!
