If you have small children, they probably bath together. The dilemma is if you have one larger bath bomb to share between them – who gets to play with the bomb while it dissolves?
Inevitably, a dust up is going to break out over control of the bath bomb. If you give each child a larger bomb, that may be too much product for their delicate skin. For my little granddaughters I made sets of two smaller bombs so each of the girls can have a bath bomb.
