#14 - make her wait in the car? You're seriously suggesting leaving a child young enough to be scared of a mascot (probably 2-4 years old) alone in a car for hours? This is not a rebelliuos teenager who decided water parks are beneath them - it's a scared child. I suggest diverting the child's attention for a little while, possibly with an ice-cream if this is a day of fun an quality family time anyway (I wouldn't normally suggest teaching a child that problems and negative emotions are solved by eating ice-cream), and once she's happy, let her know that you're going in for all the fun water-stuff now. Don't bargain with a screaming and scared child - pointing out all the fun that can be had while the kid feels like that only serves to have the child associate said fun with the scary mascot. Comfort the kid, divert her attention, then try the water park again, and keep away from the mascot. And don't let a tantrum from a child dictate the family program of an entire day.

#14, do you have sarcasm in Denmark? You'd be a great American though, rewarding fear with ice cream and sweets.

#27. You don't reward bad behaviour, you ignore it.

No one should be going for icecream or to a waterpark in this weather. I don't think any waterparks are even open yet.

Tell them the scary mascot is outside so you have to go in. Worked on my nieces and nephews. But if your child's tantrums last all day I'd suggest trying new ways to teach them self control (while they're not having a tantrum). All day tantrums suggest that they see more benefit in misbehaving than in eventually calming down.

That's why this society is in decadence, parents do what kids want instead of the other way around. Discipline is necessary and it doesn't need to come in a violent way, most of times being consistent and firm is enough for kids to learn how to behave.
