i am extremely anti-walkers. i've read some astounding statistics regarding them and injuries and i can't believe they're still on the market. it's not just stairs you need to be careful about, they can catch on things and tip over or they can roll up to counters and pull things down on top of them. i know a lot of people have them though, so it is up to you.
will she not play in her playpen or crib? i usually put finn in his crib with a bunch of toys and he'll play in there on his own for at least 30 minutes. if he's not having the toys, i'll give him baby safe household items like tupperware and cups.
