These are generally peaceful years, but that’s not to say you’ll never experience your child having heightened emotions. There are many reasons why they might seem extra emotional.
First of all, they go through big emotional changes during these years. They gain more independence, leading to frustration, especially if this independence is limited (source). They also think more about the future, which can make them nervous.
Self-consciousness also gears up as kids want to be liked by their peers. They can become emotional, low, and timid if this doesn’t happen.
Another reason eight-year-olds can be extra emotional is premature adrenarche, which is simply early puberty (source). This isn’t a medical issue — it’s just your child’s body changing at its own pace. These new hormones can make your son or daughter quite emotional.
If your child doesn’t seem like their usual happy self, create a safe space for them to discuss their feelings. Let them know that you’ve noticed they seem a bit low, and ask if there’s anything they’d like to talk about. If they don’t want to talk, ask them how you can help them.
When in doubt, contact their doctor for help and advice.
