I need help!!! My very advanced 15 month old boy is going into his terrible 3's now. He is very active and smart. He was walking at 9 months and is already talking and forming sentences. However, he is also throwing terrible tantrums and has started screaming or being very loud when we are in public and he is "over it". We got him in a tumbling class for 10-18 month olds and he hit every kid he walked up to. He hits me and occasionally bites me. Im not afraid to discipline but he doesn't listen. When I spank him he just does it again. I have a better time at home, its being in public that makes discipline more difficult. I need some suggestions on how to curb the screaming in public, and how to deal with the hitting and biting. I can't believe I am writing this, you never thought you would have to be the mom who has "that" kid. I love my son more than anything in the world, and as terrible as he can act he can also be the sweetest loving thing ever. With kisses and hugs. He's just too smart and knows he is getting away with being bad. Please help!!!!
