If a family can afford it (and by afford it I mean cold hard cash, not a new flexible friend with a big limit) then I dont see the problem tbh.
When I was a kid, we were brought stuff all the time - we got big expensive presents like computers and televisions for Christmas, birthdays we a much quieter event, but I remember us all getting a bike for no reason. As we got older then we were given an "allowance" which had to account for clothes and stuff during the month (it wasnt a huge amount of money) which made us learn to budget and value our cash.
I now have my own home, mortgage and child. I am very sensible with my cash.
