One of the reasons I started Trustle was because I had a TON of parents seeking out my support for everyday parenting challenge that would not normally want to make an appointment. In some cases potty training regressions are a great fit for therapy, but in other cases, therapy seems too intense. And, you are right, there is often a LONG wait for care (and in the US, it is quite expensive). The convenience of being able to access your dedicated expert whenever you want also helps to make progress on the challenge more quickly.
