5 pairs of underwear. Middle of real potty training. Anthony was against wearing underwear even though he was usually doing with diapers and walking into the bathroom. Except when he was doing something that he didn't want to stop doing like playing on the playground at school. One day I picked him up and he was on the play ground and had a full diaper (not full of pea) I changed it at school. I decided right then it was time to force him. I prepared him all weekend for Monday . Still a fight but he lost . Good for the parents that say they do it in a single weekend. Not Anthony . Stubborn like his mom . It took about 2 weeks to get him to put on underwear in the morn without fighting. This process will be easier and sooner with Ethan .
