If conversations with your toddler make you feel more like you're talking to yourself, don't take it personally. You'll be relieved to know there is a logical explanation behind the question why does my toddler zone out. And you can take comfort in the fact that this is a very normal occurrence.
Just like your body, your attention span develops over time. On average, a toddler can only focus on something for two to five minutes, according to Parents. Not only can this cause them to quickly loose interest in a task, but it's also why they go into their own zone. But there's one more piece that plays a role in kids spacing out, and it has to do with short-term memory.
As Psychology Today pointed out, the human brain holds a limited amount of information in the short-term memory at one time. As information is coming in, the brain is sorting it into what's called, "chunks," and there's only room for four chunks at a time. This means when you are speaking to your toddler, their brain can only make sense of about two sentences at a time. Add to this their limited attention span, and you'll see why it's so easy for these little ones to tune you out.
If you take the science behind this phenomenon and stir in some everyday factors, you'll see why it's not unusual to experience these seven reasons your toddler is zoning out.
