Hair really doesnt come back thicker using a razor, it's an old wives tale, it just looks like it at first b/c of stubble. I have shaved a lot of things and that hasnt happened in 10 years. I wish I could bleach, but my skin is extremely sensitive to harsh chemicals, it turns my skin bright red, burns like I set my skin on fire, and itches so bad, I actually used to cry when trying to do it. I dont do it anymore. But yeah, bleach is fine for a young child, I would think less scary, and I am sure most people dont break out in a rash from it like me. Glad the little one was happy!
