My step son is 15 years old and living with my husband and I full time. He is basically a good kid but he is ADHD and the oldest (my other 2 step sons are 13 and 11 and still live with their mother). My step son grates on my nerves really badly. He is basically a good kid, he doesn't get it to lots of trouble but is a KNOW IT ALL and constantly making up things and trying to pass them off as fact. When my husband is around he is much more respectful but when my husband is working and not home he tends to be less respectful and doesnt listen as well. He contstantly challenges me on bed time and eating habbits. I am currently pregnant and this is my first child. I want to know how I can be more patient with my step son. There are times that I feel like I might expect too much from him and other times that I feel like he just enjoys pushing my buttons for sport. If anyone has advise I would love to hear it.
