my parents want me to file for child support

It's always smart to have everything down in writing through the courts. That way you will know if he ever did take your child, you can have him returned quickly and your ex knows he can't just take him. As far as child support, if he can't afford it, he shouldnt have made a baby! Your child needs things and you should make sure he gets it. Good luck!

It's a good idea to take your ex to court for custody because i didn't do that and now 3 years after we split up he is taking me to court for sole custody and making up alot of stuff about me and my fiance to make himself look good to the courts.As for the child support the court will automatically put in an order for child support but it's best to have everything legal.I wish i would have instead of trusting my ex.

Yes, go to court and get it on paper. This doesn't mesn that you have to follow it to the letter, you can still bend and flex with visitation, it is just showing that if there were a problem, all they would have to do is look at the paperwork to see who should have the child. As far as child support, I would strongly suggest that you take whatever is given to you in court, I say this because I know people that have been taken advantage of because they thought their ex couldn't afford it, only to find out the the ex was getting paid under the table for his work and was only showing enough on his W-2 for the amount of the child support. In the upcoming years, anything can happen, and wouldn't you rather be safe then sorry? Plus, if you let him not pay anything, you are telling him it's ok to be a slacker and not be responsible for things he did and trust me, it will come back and bite you in the......
Hope this helps and good luck!
