I fully support you on this endeavor. The elliptical is great because you can stay in your home and do it while watching tv rain or shine and keep an eye on the little one. I think your life will radically change once you get to your goal. Always keep positive and envision where youd like to be. You'll get there. I too have jumped back onto the weight lifting and excercise schedule. Downside is soreness. Upside is great sleep. You look fantastic btw.
I like the confidence you're showing.
