I wasn't too pleased to see this article's claim that potty training takes place between ages 2 and 3. Yes, that is when it starts for most children, but many need to continue the process a long time, unfortunately. For example, some are afraid to do #2 in the potty, and you cannot force it, and it may happen when they much older than 3. It's not the parent's "fault." There may be a medical reason, so check with a Pediatrician, or it may be anxiety the child needs time and patience to overcome. If you are a parent of a child who is older than 3 and still potty training, don't feel alone. My son took until 3-yrs-and-8 months old, and knowing him, I wonder if a regression will happen. I wish so many Internet articles wouldn't say children will train by age 3 or 4. That's just not true for all children.
