You might want to talk to the daycare and see what protocol they follow to assist with potty training. I had my son in a mmo 2 days a week and when he was there he went backwards he wanted to wear a pull up he was 3 just a little over and honestly I think it's easier for them for just change him then deal with taking him or sending him to the potty so I talked to the teacher and said hey look we're in this together and I need your help for re-enforecement with the potty. Sometimes my son just didn't want to take time out to potty having too much fun. I started him at 2 1/2 he was back and forth about it but he's now using the potty all the time. I wouldn't let it go past 3 yrs old I did with 2 of my children and it's harder to potty train then. It's also not good to hold urine. When we go to the potty at a public place I always reasure my youngest I will be with him you don't want them to not go to public places or it starts a whole cycle of other issues. Anyway I stopped buying pull ups for the mmo school and gave him and them no choice use pants. I'm glad I did they didn't want him to have a accident then. There are some preschools that at certain ages will not accept a child that is not potty trained even at 3 yrs old the one I went to well, they hope by age 4 the child is potty trained. Good luck I wish you much success at this venture.
