Do you organise a birthday bash for your child every year?

For my first child, I hosted a big birthday bash for his first birthday then subsequently, I held a small one just with close family with a cake of his choice and dinner at a restaurant he chose. For my second born, it should be the same. A big first birthday bash then subsequently a small one. I feel that there is no need for a big bash every year when they can hardly remember. I will rather spend all my time during their birthday with them rather than spending my time on entertaining guests.
