Unwed Father Needs Advice

My girlfriend and I have an 11 month old daughter and she moved out 2 weeks ago with her new boyfriend. She is requesting that I purchase all my daughters diapers, formula, clothing and I also carry insurance on her. I am afraid if her new relationship doesn't work out she will try to then sue me for back child support. How should I handle child support prior to court order? I live in Louisiana and she has moved back to Texas.
