Always a good idea to start potty training with a small potty, so you can offer a choice if your toddler isn't okay with the toilet to start. A small potty with back support is especially helpful for the littlest littles, and for toddlers struggling to sit and relax...to release.
Any ways you can normalize poop, and how everyone poops, is helpful for a toddler (to make it feel less scary). But to be honest, this game is just plain fun, potty training or not. Who knew what wombat poop looks like? (Hint: it's square!)
Toddlers can have big feelings. Here's a great way to connect with your child about emotions and ways to cope with big feelings, whether it's about this new process of using the potty or the new baby in the house.
