If you can find a small spoon that gives you an acceptable dose, do it. It is 10 times easier than using a scale.
This is why I made a pump system for our products, cause the weighing is nonsense.
If you can make it so that you dose one size spoon on one day and one size on the other day, life will be easy enough. If you need different size spoons on the same day, get enough for everything you dose. Then you can leave it in the bag/box/etc and it will never have to be thought about.
