Distinguishing if your child is spoilt or not is actually a lot harder than it seems. When you see a kid throwing tantrums in NTUC while you're grocery shopping, you may (in your mind) label him/her as a complete brat, but you probably wouldn't with your own 4-year-old.
You'd probably think about why he is kicking up a fuss (he must be in need of a nap, snack, playtime...). You'd almost never see yourself as spoiling him or rewarding his bratty behaviour.
But when your child shows unfavourable behaviour — whether it's age-appropriate or not — it's time to make some changes to put a stop to it.
