That's what some kids feel about learning to use the potty. The baby bird knows it has wings, but it doesn't know what it can do with them. Kids know they go potty, but they don't know they can control how they go potty. As parents, we need to give our kids a chance and be patient.
The fact that as a parent we really want our child to concentrate on learning to use the potty sometimes causes us to overlook the obvious. We get all stressed out about it and forget that the first thing a child needs is to feel that using their special potty is a safe thing. So creating a safe and comfortable potty environment is very important. We kept favorite books in a pile next to the potty to make it have a warm feeling. Let your learner bring their friends--favorite dolls, lovies, toys--with them to the potty just to make them feel safe and comfortable. As each child learns to speak or walk at their own speed, so will each child learn to potty best at their own rate. Pressuring them is not going to make them learn to use the potty faster.
