Birthdays are special days. Children celebrating their birthdays are usually given parties. At age 1, 7 and 18, they have grand celebrations. Well, usually though there are those who celebrate in a grand way year after year.
We don’t celebrate our children’s birthday in a grand way. We don’t even have halloween costumes since they don’t really participate much during Trick or Treat.
I hope the children will not get back at me when they are grownup for not having big grand parties for them during their birthdays 😛
We usually celebrate by offering and going to mass and a quiet dinner at the restaurant of their choice.  And if the gift they like is within the budget then “why not?”
