Boyfriend wants me to learn spanish.. HELP

Alright, so my boyfriend and his whole family are from Mexico. With our daughter on the way, he really wants me to learn Spanish so that we can both teach it to our little girl. I am in need of some advice and tips on learning. I started back in March, and the only thing I have been successful with are certain words. And even then im too scared to use them because I'm worried ill pronounce it wrong. Help please! What's the easiest way to learn?
