No Gift Yet

My kids both celebrated their birthdays this week. My son turned 4 last Monday while my daughter turned 2 today. I still don’t have a gift for them and I have no idea what to give them. I’m thinking of giving them bullion that could served as part of their savings and since they don’t know how to spend money yet, they won’t be able to use it and by the time they need some money, its value has increased already. But then I’m also thinking if they will appreciate it since they have no idea what it is. So what I might do is to get both of them a bullion and then buy a toy that they will like. :)
