You don't legally have to put him on the birth certificate, which if I'm not mistaken means he doesn't have any custody over the child. Do everything you can to protect that baby, though! He sounds like a deadbeat.
That point is that you have facts and can bring them to court and the judge always looks at it from the mothers side first just cause naturally the baby belongs with the mother. I know from going to court with my siblings and hearing my parents talk about it
We had gotten into a arguement n he had said dat he had stuff against me to make me seem like a bad parent, i knw he doesnt but even tho he brought it up it made me feel like i gotta protect myself n be ready so i do save all his post. But wat if we go to court n hes clean , n he says he quit ?
I can only speak for how it is here in Sweden... Here YOU can get in trouble if you let your baby be around a person who is an addict. The social services would be able to take your baby away.
The mother has the legal custody and if the father has this kind of problem, the law says that he should not even visit the child.
It's best you go to court right away even if you guys aren't really broken up just to protect yourself in the future. And having proof that he smokes and him posting them on social network could get him in trouble and it would help you out ALOT in court and you not wanting him around your guys child for smoking weed is good enough for the judge to give you custody especially if he's not showing hes willing to stop or slow down anytime soon. I have lots of friends and family who smoke but put their children first and don't bring it around. So far i think your doing a good job. But myself personally i live in California and i do smoke weed and have a medical marijuana card but when i found out i was pregnant i stopped and after my baby i plan to slow down and only do it when i have alone time with my bf. Weed is the opposite of bad for you but i do understand why you are concerned especially that it doesn't seem he has his life together yet.
