Many of you may disagree and that's OK....I have been exactly where you are and know how hard it is....each child is different and to say I don't know when they are very young may be all the answer they need....because the truth for me was I did not know why someone would choose to use drugs over their family, especially the children.....for me I would stop at it is not your fault and leave out the daddy loves you.....children need to know if you love someone you treat them with respect, you take care of them, you are there for them....even at a early age they pick up what is acceptable...JMHO...
