I am not a believer in letting chilcare do most of the work. As a childcare provider I am sure you can imagine why! I am a newer convert to the 3 day potty training method by Lora Jensen. Its finally the ideals I have tried to propose to parents for so many years , all in one guideline. Its not the "bible" by any means, but for me it is what I encourage my families to do and tell them of my success rates in the last year or so with several families (kids ages 22 mos-29 mos).
Its like potty boot camp, and for me, shows the parental commitment to the process that I need to see. Its really NOT my job to potty train your child..but to support and assist in this endeavor...but we do need to be on the same page.
This method requires parents to take a 3 day weeknd or time frame and FULLY commit to the task. Toss all diapers and pull ups (crutches), have everything set to not leave the house at all, to not be more than a few feet from the child the entire time (simple meals cooked or ingredients on hand)..no major tasks like cleaning to do or working from home, yard work, etc...NOTHING but be with and commit to your child in this endeavor.
Many pairs of undies, sheets for their bed, towels about the house to catch piddles...have them wear a tshirt and undies...and to only go potty in the bathroom..not to have potty chairs strewn about the house. The idea is to get them to tell you when they need to go...you won't be taking them at timed intervals..you would be reminding them "let me know when you need to go potty" "make sure you tell me when we need to get to the bathroom"...instead of constantly asking "do you have to go potty"..to which they will always say"no". You will quickly learn to read their cues...a whine, a wiggle, etc...then help them learn to understand it to and to celebrate the success!
Your job is to be his guide...not just assume he will figure it out, nor to assume that daycare will do the job for you. I am sorry...but this attitude irritates me. Sorry...too many years of parents thinking that I will just potty train their child, while at home they continue to use pull ups (the worst invention as far as I am concerned) and diapers, because its easier or they are too busy to take the time and slow down and do this important transistion with their child. So what if they still actually need you to go to the bathroom with them each time to assist with pants, postioning and handwashing. I have no issue with that here at my home childcare. Its better than changing the diapers of these older children. And their sense of pride at wearing those big kid undies and working toward that independence....totally worth it!!!
Good luck! Find an approach that works for you and just do it!! You can do this!!!
