A step stool is a very convenient item to have in the bathroom and around the house if you have a 2 or 3 year old. We have one in the bathroom that is used for brushing teeth and pulling up to reach the light switch. Toddlers like to be able to do things themselves, and having that extra foot provided by a stool makes a big difference when completing small (but essential!) tasks like turning out the lights.
I love this chevron stool because it is neutral, preppy, and can add a little mini style to whatever room it calls home. It's available on BelleAndJune.com in gray or blue chevron, and there other pretty designs for step stools as well.
