I think it's un-fair to lump ALL young parents together. I am a young parent. I have two sons, ages 2 and 11 months. We wake up at 7:30 each morning and they always get a good breakfast. Yesterday was pancakes and bacon. Today, oatmeal with bananas. Tomorrow may be cereal and strawberries or eggs and toast.
It almost sounds to me like you are speaking from a place where there is a young parent in your life and you find yourself picking up the slack and resenting it.
