Do you Give or Buy Gifts for your Sims?

I do buy birthday gifts for my sims. When the first one ages up to child, if the household can afford it, I'll buy playground equipment for them, adding new items as each younger sibling ages up, plus a bicycle in their favorite color, a tablet to do their homework on, and at least one skill item to fit whatever their traits are. Sometimes I have the parents each give one of the gifts to them. When they age up to teen, they'll get a new bicycle or a car of their own, if there's room on the lot to park it and money to buy it, and any skill and recreational items fitting their traits that they couldn't use until they reached that age. I don't usually buy graduation gifts, but the family does celebrate with a meal at the bistro after graduation. As each child grows up and moves out on their own, they take those gifts along with them. If there's something they can't carry in their personal inventory, I'll place an identical item in their new home before they move, and delete the one they're leaving behind.

Everybody also gets their favorite meal on their birthday, unless there's nobody in the household with enough skill to cook it.
