I bought a small one for our (bigger than average) 1 year old for Christmas, when it arrived I was skeptical that it would last for long but once he was on it I could appreciate that although it looks small it's quite wide so his feet only just touch the floor, not enough to get any real push from the feet. S likes to push it around as a walker at the moment and loves sitting on and being pulled around. I think it's going to get a lot of use of over the years and I'm really happy with my purchase.
His Granny bought him an ride on from ELC and I genuinely can't see it having a long lifespan, it's quite restrictive re turning, at the moment he can only go forwards as he doesn't understand the "steering wheel" and it's plastic which I hate.
