It is normal for me to have breast milk if I am not breast feeded never had and I have the mirena my son is one year in a half

How much milk are you talking about? If you are talking about milk gushing out, then no, it's not normal. However, if it's a trace that comes during nipple stimulation in sex, then could happen. Even if you never breastfed, your body still makes milk.

If you have another baby, sounds like you should definitely consider breastfeeding, as your breasts obviously make plenty of milk.

If you want to get rid of it, try some sage tea.

My son is a year and a half and I never breast feed him, it is when ever you touch my breast a small amount comes out and I have had the mirena in for over a year

The Minera releases a small amount of the hormone progesterone which is involved in milk production. Normally, the amount is small enough that it should not cause milk to be secreted, but as you've had a baby, and if your sex life involves a lot of breast or nipple stimulation, this could be enough to keep your milk supply going.
