Meth baby - what to expect?

We were placed with a newborn baby boy who was born positive to meth and he is the best baby in the world. He does sleep a bunch even now at 4 months but is the sweetest and happiest baby I have had. I agree that every case is different but I thought I would share my experience with you. Oh yeah and as far as gaining weight, well he just turned 4 months and he weighs 20 pounds. :O Our little guy loves to eat! I wish your family the best of luck and will say a prayer for them.
