Get your house, your car and your self ready. Set up a designated potty area for consistency, buy ALOT of underwear. I do not recommend pull ups other than nap time. The child needs to feel wet and dirty. If you have a lot of carpet or furniture that can easily stain I would suggest that you put the underware on then have a pull up over it. That way the child will feel wet but it won't get all over the house. I always packed a potty chair, plastic bags, wipes, Clorox wipes, changes of clothes and potty treats in my car because you never know when you may need it. We used the car potty often in our potty training years. Make sure you always have a watch, timer or clock to keep track of the last time he went potty.
Read books about going potty, have your child go in the bathroom with you ect. Jaymie a mother of 2 and teacher told me an experiment that she did to show her daughter what happens when she had a full bladder. She filled up a cup all the way and walked quickly across the room. Obviously, the cup spilled. This is how she explained that if you wait too long the go potty your bladder would be full and leak or spill.
This is extremely important that you teach your child to wipe themselves and wash their hands themselves. Parents think that their children simply "can't" wipe themselves so they do it for them. When in reality this is crippling your child and will cause problems later in their preschool years. As parents it is vital that we teach our children independent skills. To teach a child to wipe you show the child by placing your hand on his and talk about what you are doing while you are modeling it. The next time you allow them to do it while you supervise. Encourage them to keep wiping on a clean part of the paper until their paper comes out clean. Also, tell them to wipe from front to back.
