You never want to wash your locks themselves. No matter what soap you use. All you want to do is scrub your scalp. When you rinse, the soap will flow throw your hair.
For baby locks, I usually say go with liquid soap. Liquid soaps are not as rough on your locks. When they mature and are not inclined to untangle when manhandled, you can use a bar, but you could keep using liquid if you still like it.
