Saturday the 7th, was my baby shower at my mothers house. All my family was there. Everything went over pretty well. Until the kids started in on my 4 year old son. Let me explain, my son has been potty trained for about two years now. We live in a two story apartment and the bathroom is up stairs. At first he would come tell us he had to go #2 and we'd go upstairs with him, cause he won't go upstair by himself. But recently he has gotten in the habit of not telling us and holding it. Holding it until it just builds up until it is so big it hurts to come out. We've tried everything!!! Well Friday night he would go hide and we knew he had to go, so we'd take him upstairs. We did this 4-5 times. No success. We gave him a stool softener and still nothing. We got up early the next morning and he sat on the toliet again, nothing happened. We went to the shower and like I said everything was fine until I saw my husband carring my son to the bathroom crying and shaking. I went back there and he was so upset and shaking so much, I couldn't understand what he was saying. When I finally got him calmed enough, he explained that he two cousins had him pinned up against the fence in the back yard laughing and making fun of him because he did #2 on himself. They had my son so scared he didn't want to leave the bathroom. he told me he hated his cousins. I told him it was very mean what they did, but he couldn't hate them. He finally calmed down enough to join the party again, but very shyly. I went and found my nephews and told them that they didn't have a right to be meanand nasty and i wouls spank their butts if I hear of it again. OOOO I wanted to tear them up. I then told my sister in law, their mother. She blamed it all on the older son and said they were just being boys. It made me soooooo mad I had to walk away before I DDT'd her. I really wasnted to take her down. But I didn't I walked way. She didn't do anything, she didn't even go talk to her boys. What should I do? #1 About my son and him holding it when he has to go. #2 About the whole situation at the baby shower? I'm still angry and my son is still messed up from it. He won't allow anyone to laugh even if it's at the TV. And he keeps telling me he doesn't want to see his cousins anymore.

please
