I am a young mother of two boys. My youngest is two months old, and my oldest is 3. I'm having a difficult time potty training my oldest. It seemed like he almost had it down before my youngest was born, but he challenged me even more with the training after seeing his brother wearing diapers. I have tried many ways to get him to go at home, he only goes at school with other children doing it as well. He knows how to use the toilet, I just do not know what to do to encourage him to. He fights me and screams. I am so tired all the time, is there any suggestions from anyone? Thanks!!
