Having the skills and knowledge required is extremely important in being the best parent you can be. The more you educate yourself and gather information, the more effective of a parent you will be.
Clear off a space on the kitchen counter, have your child lay down, and run water from the faucet over the hair and scalp. This makes things easier for toddlers who are afraid to dunk their heads dunked in the water or have water poured on them.
While it is true that your children need and deserve your time, you still need "you" time. This allows you be yourself and a parent.
