My daughter will be 4 in 2 weeks and has been potty training for 2 1/2 years. Right around 1 1/2 she wanted to start using the potty. We encouraged it but didn't push it at that point (mainly going before bath, bed, etc.). She has never been completely potty trained because she cannot seem to hold it. It has been months since she has had a complete accident where she floods, but anywhere from 2-8 times a day she will wet enough that it goes through her underwear and pants. Always when this happens she still goes a lot in the toilet. She never seems to recognize that she needs to go until she has "leaked" some out. Now that she is getting older (and her 2 year old sister is potty trained) she is very aware and tells me often that she doesn't want to leak in her undies. We have tried EVERYTHING, sticker charts, timing it (anywhere from every 15 min to every hour) and nothing seems to work. She does not seem to drink an excessive amount. Many times when we time it she will try to go and then 10 minutes later she is wet.
One thing we have found to help is making her sit and relax (we usually count to 15) and then she will go. Otherwise she will sit down and say she can't go and try to get up. I am at a complete loss as to what to do and it can be very frustrating. I try my hardest not to let her see that I am frustrated because I know that does not help at all but I am to the point where I cannot take much more!
