I remember the bias; in my case I was never sure whether it was because I was the only father at the local playgrounds, or whether it was because I was the only foreigner there. But I will say that while children don't understand words (so much at the start) they really do pick up on tone of voice, and emotion. Sometimes there's an instinct urge to shout "Nooooo!!!! Stop!!! Don't do that!!" when a baby/toddler starts doing something dangerous. It'll happen when you least expect it - don't beat yourself up, and try to remember to speak calmly and clearly.
