nobody put any ideas I my head...it’s just a general wondering, like most mn posts! No, it's not like most MN posts. No way.
Well it's clear you aren't sure what is sensible parenting.
Why do you need to ask if something is 'enough'? What is the yardstick for measuring it?
Most parents I know choose one or two presents for children of that age. Showering them with plastic rubbish is madness. More doesn't equal better!
As I said, it's not the amount you spend it's the thought behind it and the worry that it's 'enough'.
Do you honestly think children of the age yours are have any notion of the value of money? Really??? They don't know if something costs 50p or £500.
Or are you building up expectations in them that they need to have X amount of presents?
You've already said that they are influenced by the amount of presents their friends at school have.
You need to teach your children real values, not measured by the £££ you spend on them.
It's far more caring to choose one or two small gifts that have some meaning for them and that they will love, rather than zillions of cheap tat that they won't value.
What was your own childhood like? You seem to have no idea of how to parent.
