Calling all photog bees + photography hobbyists!

I got a DSLR for Christmas and recently used Amazon gift cards leftover from the wedding to upgrade my lens.

Now I have a few Visa gift cards left and DH agreed I could use them to get some photo editing software.

I'm trying to decide between Photoshop and Lightroom.

My main criteria is that it be pretty user-friendly, since I'm a novice. However, I want it to have the capability of helping produce professional-quality photos, since I'm thinking of trying my hand at birth photography eventually.

Thoughts? Experiences? Recommendations?
