Yes, I do use both, I'm sorry I worded that question wrong. I have started using Lightroom first and then doing the detailed finishing work in Photoshop. I'm comfortable with Photoshop. I do a lot of newborns and it can become tedious. Right now I'm doing every picture individually, like you said.
If it's becoming tedious, I'm guessing you're shooting too much. I don't shoot newborns (heck, I avoid even talking to children unless they're at least old enough to drive), but if I were to do a one hour newborn session, I would anticipate shooting 50-75 frames, binning at least half of those and offering the client 20-30 proofs (which only have cropping & colour correction) from which to choose. If they want to pay me to process all 30, I'm happy to do that, but my typical client (for retail/family photography) purchases 6-8 images at most. I can't see newborn work being vastly different.
