There are many factors to consider. Sizing, most walkers do take up a lot of space so be sure to find one that can collapse into a smaller size for storage if you can’t afford losing space. You should also consider what stage your child is at developmentally so you know which features of a walker are most suited for them. Also, consider which kind of walkers will work best with your flooring. If you have carpet, maybe consider one of the walkers that has an easier time moving across the carpet or rugs.
