I set Eli in the basement yesterday so I didn't have to set up a baby gate, since he hasn't (ahem, hadn't) made it past the 2nd stair yet. Not one minute later he was happily playing with his toys at the TOP of the stairs. Whoa, buddy! I suppose gates are a fact of life for a while, then... but when to let him learn on his own? Patrick didn't have any stairs to practice on until we moved into this house when he was 18 months old, and the first day we lived here he fell down them, head-over-heels, pancake-style. So this is new territory, please let me know if you have any suggestions! For now, gates - he gets enough tumbling thanks his big brother wrestling him!
