My daughter is now 3. Is she fully potty trained? Well, yes kind of sort of, um I guess the right answer is no. When I hear parents say that they potty trained their child in 2 days, I am baffled. When should you start potty training? What should you do? What are some tools you can use? When should you not potty train? Because this is such a huge part of toddlerhood, I wanted to ask my sister Dasy Perez (18 year experienced preschool teacher) for her advice on the matter.
