Child support and baby

butterfly

Should I wait until my baby is older to file for child support she's just a newborn and the father is not good or his family. I care about her safety more. I also have a 5 year old. My ex left us for another woman and the lady picking with me but claim she will do my kids right. Idk what to do y'all. My mind tells me leave it alone. Then it says get full custody. Or supervised visitation? Help. The ex smokes weed that's why I don't want kids around
