As grandmothers, we carry a special role in our grandchildren’s lives—one of unconditional love, storytelling, treats, warm hugs, and wise guidance. But sometimes, that guidance calls us to step in, gently but firmly, when we notice our grandchild developing behaviors that could harm their character or future.
Now, let’s be honest—it’s easy to ignore a snarky remark or a little fib here and there. We may even chuckle at sass or blame a tantrum on a bad mood. But some habits, if left unchecked, can grow into lifelong struggles. And one of the most loving things we can do is help our grandkids become better people—even when it’s uncomfortable.
So here are 12 bad behaviors that we, as grandmothers, should never overlook—and the ripple effects they can cause if we do.
1. Lying, Even the Small Kind
When your grandchild tells a fib about finishing their homework or insists they didn’t knock over the juice you clearly saw them spill, it might feel like a small thing. But lying, even in the tiniest forms, is like a weed—if it’s not pulled early, it spreads.
Repercussions: Lying damages trust and teaches children to manipulate situations. Over time, they learn to avoid responsibility and accountability. In relationships, work, and friendships, this can become a serious problem.
Your response: Stay calm, but be honest. Let them know you value truth over perfection. Praise them when they tell the truth—even if it gets them in trouble. This builds integrity.
2. Disrespectful Behavior Toward Adults (and Peers)
Backtalk, ignoring adults, eye-rolling, and sarcastic tones might seem like “just being a kid,” but they reflect a deeper lack of respect. And if they learn that talking that way is acceptable around you, they may think it’s fine everywhere.
Repercussions: Disrespect leads to problems in school, jobs, and friendships. It makes others uncomfortable and can prevent your grandchild from forming healthy, trusting relationships.
Your response: Correct the behavior at the moment. Model respectful language. Explain that disagreement is okay—but how we express it matters.
3. Bullying or Teasing Others
If your grandchild laughs at a sibling’s mistake or mimics another child to get a laugh, that’s not harmless humor—it’s a lesson in cruelty in disguise.
Repercussions: This behavior can snowball into true bullying. It also damages their own self-worth because cruelty often masks insecurity. And it teaches them to seek power by putting others down.
Your response: Ask them how they would feel in that situation. Teach empathy, not just manners. Let them see the importance of kindness and give praise when they show compassion.
4. Avoiding Responsibility
Some children blame others for their actions or flat-out deny their part in things gone wrong. “It was the dog!” “My brother told me to!” “I didn’t mean to!”
Repercussions: If they never learn to own their choices, they won’t learn how to grow from them. Avoiding responsibility leads to immaturity and weak character.
Your response: Gently guide them to take accountability. Explain that everyone makes mistakes—but only strong people own up to them. Make responsibility feel empowering, not shameful.
5. Hurting Animals or Insects for Fun
This one is serious. Whether it’s pulling a dog’s tail or stomping on ants for fun, cruelty to animals should never be brushed off.
Repercussions: Studies show that cruelty to animals can be a warning sign of emotional trouble. It also reflects a lack of empathy and can evolve into more violent behavior over time.
Your response: Step in immediately. Explain that all creatures feel pain. Encourage them to show kindness and teach them how to care for pets or respect nature.
6. Stealing
A cookie taken without asking may not seem like a crisis. But taking something that doesn’t belong to them—even small things—can lead to bigger issues.
Repercussions: If not corrected, stealing teaches children that rules are flexible when they want something. It can evolve into dishonesty and disrespect for others’ property.
Your response: Don’t overreact, but don’t ignore it either. Talk about why it’s wrong, and guide them through returning the item and apologizing. Reinforce the value of asking and earning.
7. Using Inappropriate Language
Kids are little sponges. They repeat things they hear at school, online, or from older siblings. But swearing or making inappropriate jokes shouldn’t be tolerated just because they “don’t know better.”
Repercussions: Inappropriate language can get them into trouble at school, embarrass them in public, or create a pattern of speaking without thinking. It also makes them seem more mature than they really are—and not in a good way.
Your response: Set boundaries. Explain in simple terms why certain words aren’t okay for them. Suggest better alternatives, and don’t reward them with laughter when they cross the line.
8. Screen Time Obsession and Rudeness
If your grandchild can’t tear their eyes off a screen, ignores you when spoken to, or throws a fit when asked to turn off a device, it’s time for a reset.
Repercussions: Tech overuse leads to shortened attention spans, social isolation, and stunted communication skills. It can even affect emotional regulation.
Your response: Be intentional. Set tech-free times during visits. Encourage board games, baking, crafts, or walks. Let them know that people come before pixels.
9. Throwing Tantrums to Get Their Way
Yes, even big kids do this! Whining, yelling, slamming doors, or sulking when things don’t go their way should never be ignored.
Repercussions: If they learn tantrums = results, they’ll use emotional outbursts as a strategy long into adulthood—hurting their future relationships and emotional health.
Your response: Stay calm. Don’t reward the outburst. When they settle down, talk through what they felt and offer better tools for handling disappointment.
10. Talking Behind People’s Backs
Gossiping or mocking others when they’re not around might seem like harmless chatter, but it teaches dishonesty and judgmental thinking.
Repercussions: It can make your grandchild feel powerful in the short term—but eventually, people will stop trusting them. It also fosters negativity and insecurity.
Your response: Teach them to speak to people, not about them. Ask if what they’re saying is kind, true, and necessary. Encourage them to speak up for others instead.
11. Entitlement and Ingratitude
When a child expects gifts, whines about what they didn’t get, or refuses to say “thank you,” it’s more than a lack of manners—it’s a sign of an ungrateful heart.
Repercussions: Entitlement leads to a life of dissatisfaction and constant comparison. Gratitude, on the other hand, leads to contentment and resilience.
Your response: Create gratitude rituals, like naming three things they’re thankful for at bedtime or writing thank-you notes together. Help them realize how much they already have.
12. Blatant Defiance
If your grandchild is starting to push boundaries by deliberately ignoring you or refusing to follow your rules, don’t take it personally—but don’t ignore it.
Repercussions: Boundaries exist to protect and guide. If they learn your “no” means nothing, they may carry that same attitude to school, with authority, or even in dangerous situations.
Your response: Stay loving but consistent. Let them know your rules come from care, not control. Be clear on consequences and always follow through with grace.
In Closing: Don’t Let Love Be Silent
Correcting your grandchild doesn’t make you a mean grandma. It makes you a wise one.
The truth is, discipline is love—when it’s done with patience, clarity, and warmth. It’s not about yelling or punishing. It’s about guiding. Shaping. Helping them grow into someone who knows right from wrong, and who chooses kindness and integrity, even when no one is watching.
We may not be their parents, but our influence is powerful. Let’s use it to build not just happy childhoods, but strong, beautiful futures. Because they’re watching us. And they’re learning more from us than we may ever realize.
