Because I buy my children presents that I chose for their birthdays.
In our house, children get presents they ask for for Christmas, and we chose them things they would like for their Birthdays (They all have birthdays within 3 months of Christmas). I put thought into the presents and pick carefully and the children have never had an issue.
Another Mum in the playground has said its a bit controlling to not let them chose what they want.
Dont other people do it this way?
