My daughter had a wooden toddler trolley, which I think is different from what most people mean when they say walker (though in my brain they're the same), basically a cart to push around rather than something to sit in and walk. She enjoyed that and actually still pushes it around with her toys in it now at 2.5. We didn't have any of the sort of activity centre like toys (where you sit them in the middle, like a jumperoo). She was quite happy to just be on the floor with things to play with.
