This isn't about my child and she doesn't need protecting. I used her as an example because in regards to potty training, she fell well within the average.

She wasn't delayed. She wasn't an outlier. She was average.

I'm arguing your point because you keep insisting your experience is average.

It is not.

Don't take my word for it. Google it.

You'll see.

Never mind. Here. This is straight from the Google AI Overview on the search phrase "potty training age"

The average age for children to start potty training is between 2 and 3 years old, but most children aren't ready until they're between 18 months and 3 years old. However, the age at which a child is ready for potty training depends on their developmental skills, focus, and signs of readiness. Some signs that a child may be ready include:
Asking to change their diaper
Showing discomfort when their diaper is wet or dirty
Having dry diapers for at least two hours during the day
Being dry after naps or overnight
Following parents or older children into the bathroom
Wanting to please parents or get praise by using the potty.

If your daycare has that requirement, its because they were either understaffed, hoity toity, half day establishments, actually a preschool instead of a daycare, or something like that.

Here's what Google reports on preschool requirements for potty training, on average:

Preschool Potty Training Requirements
In general, most programs for children ages three and up will require that your child be potty trained before starting. Programs for younger children often won't require potty training and will provide information regarding how they assist in the potty training process.

Here's where definition of potty training will be a little less stringent than what kindergarten will require. Preschool is mostly asking that the child knows when they have to go and can tell adult when they have to go.

They'll be escorted (depending on facility and location of bathroom in regards to their classroom) and assisted as needed.

But kindergarten requires you to do it completely independently.

And no, I don't care what your opinion is. Like I said my daughter doesn't need defending for being average.

I just don't want someone else to read through this and think they're a failure at life or a bad parent or whatever based on what, in fact, is wrong information and they or their kid was fine and well within average all along.

Your opinion is not fact. Your experience is not the mean or within average. It only applies to you.

It would be fine if you weren't insisting that your experience as an outsider is the average.

It's not.

Check the stats.
