As a Mom and a childcare provider, I have seen this happen a lot at that age. It appears that the child becomes comfortable with the whole toilet learning scene and waits too long to get to the restroom in time. I mean, really, which is more fun, playing or stopping right in the middle of fun times and heading off to the toilet? I have had success with putting the children in charge of the clean-up. This might sound mean or unsanitary, but I do check to make sure they are clean enough. If it is honestly an issue of the child not wanting to be inconvenienced, this does tend to alter their thinking. I think it is also important for them to complete the transition of understanding that it is their job to take care of their elimination, not yours. I cannot tell you how many times a child has called me into the bathroom to take off their wet pants because they "don't want to get their hands wet and icky." I calmly (and kindly) tell them that I do not like it either, which is why I always make sure to head to the toilet in plenty of time to go. Of course, I make sure they are honestly able to accomplish the task on their own. I stay in with them and encourage them, step by step, in taking off their wet clothes. I show them how to wipe until the toilet paper "stays white." I think this is a critical teaching moment for both of you. How you handle this could speak volumes about how your relationship will be defined in the future. It is absolutely important for you to be there for your little ones, but it is also empowering for them to discover that they can do things on their own. What is temporarily frustrating can end up as a stepping stone to a confident, capable child. God bless you and yours, and I wish you all the best!
