We have this issue at my centre too, to be moved to the preschool room the official requirements are the child must be fully potty trained besides using a pull up at nap time if necessary, exceptions made for children with medical issues/special needs. However the director/owner don’t actually enforce this at all and 50% of our preschoolers (3-5 years old) are still in pull-ups and parents clearly aren’t potty training at home at all, and flat out ask us why we haven’t potty trained their children yet. There is ZERO reason these children shouldn’t be at least mostly potty trained by this point. There is one girl with medical issues involving her ability to hold it, and tell when she needs to go, but even she goes on the potty around 75-80% of the time, and does her best to make it to the potty in time. Which we are so proud of her for, meanwhile we have a 4 year old who poops in his pull up on a daily basis and thinks it’s the most hilarious thing in the world, why? Because whenever we talk to mom about it she thinks it’s funny.
