Effect of Drugs on Baby?

Both my children were exposed to Meth and Marijuana. One thing I notice is strong sensitivity to just about everything. This is something I battle in my own life (I was exposed to marijuana). Sometimes I feel like my clothes are made of sandpaper. Loud sounds hurt. Bright lights make me cringe. Strong tastes are painful and cause me to gag easily. All tags have to be completely removed from my clothes. With my kids, I just had to isolate what was bothering them and change the stimulus. There was lots of swaddling involved with my daughter. In my experience, Meth tends to cause problems with attention and behavior. My son has poor impulse control but I am working on it with him. He is only 3 so I am sure I haven't seen the worst of it. I have no experience with cocaine exposure.
