During the Wait: Learning to Speak Mandarin

I do believe learning to speak Mandarin Chinese is going to be a challenge for me, but I'm willing to give it a shot and learn a few key phrases, songs, etc. Not only is it a difficult language [by the fact that it's completely different that anything I've ever spoken or written or even heard spoken for that matter], but it consists of 4 tones...and I thought that the Southern dialect was complicated. This is a great resource for the easily-intimated, linguistically-challenged, such as me. Take a listen and have a go at it. So will I be considered trilingual if I learn Mandarin, and baby signing? Let's not get ahead of ourselves here.
