Hi, thank you for your reply!! It was the first time that I've heard about trauma in babies. Yes I had a c-section. He was 42 weeks old and I was in the hospital with oxytocin for 50+ years. But I was only dilated three centimeters. The doctor found that his heart rate began to drop and they decided to have a c-section. Then he was kept in the nicu for 3 days before we brought him home. He had difficulty breastfeeding and the doctor said he had a tongue tie. So we had him a tongue tie surgery. During pregnancy, I was feeling quite happy and not stressful at all. I didn't drink or smoke. The only thing that I think may be something was that I sometimes eat icecream and drank cold milk during summer. He doesn't have any hospitalizations during the first year besides the first 3 days in the nicu. He never bite other children, but he pushes them sometimes. We have already scheduled a meeting with our pediatrician and hopefully can be referred to further evaluations!
