From birth to age two is a child’s sensorimotor stage of development. During this age, children are hard-wired to explore their environment using all of their senses. This means they will touch, pick-up, grab, bite, pinch, throw, smear, and put absolutely everything they can into their mouths in an effort to understand the world around them. This exploration may mean that someone gets hurt, property is destroyed, or the child’s own safety is compromised. It’s not purposeful, and it’s not malicious. It’s simply a baby’s underdeveloped instinct to learn.
It’s tempting to think that the more often or more firmly you tell a young child no, the more she will remember it and behave differently next time. But a one-year-old child does not have mature enough brain development to stop herself from adhering to a no. So, no matter how many times you tell her, she simply does not have the neural connection to stop, remember your words, think through the options, and decide not to act. It’s not that babies don’t listen, it’s that they lack sufficient brain development to acknowledge, comprehend, and think logically about a “No.”
