DD1 never got it...wasnt on the schedule when she was born and she always gets it bad.

DD2 did have it and when ever DD1 has it, she only has a very minimal case, if at all

DS has only had the 2 month dose so far.

IMO its well worth it.....just seeing the difference in my 2 girls and how severe one gets it and the other hardly anything at all....i think its helped in the long run. Even better its an oral thing not another needle!
