When I have a kid who is at the age for pottying and shows all the signs, I inform the parents they seem ready and tell them to let me know when they are ready to get on board and work at home as well as me working here. If i begin training and inform the parent but they keep dropping off in diaper or pullups and when i ask they give me the careless response of, we are just not getting anywhere at home, or the famous "i ask them if they have to go and they said no", i will gently remind them it's not up to them, we have to train them to go to the potty and it cant be their choice. if i get a parent that just doesnt seem to be on board, I will just inform them.....let me know when YOU are ready and I will follow your lead.
It's not worth wasting your time if the parent isnt taking the time at home!!!!!!!!
