Famous quotes containing the word leach:
“Guilt is the most destructive of all emotions. It mourns what has been while playing no part in what may be, now or in the future. Whatever you are doing, however, you are coping, if you listen to your child and to your own feelings, there will be something you can actually do to make things right.”
—Penelope Leach (20th century)
“For a small child there is no division between playing and learning; between the things he or she does “just for fun” and things that are “educational.” The child learns while living and any part of living that is enjoyable is also play.”
—Penelope Leach (20th century)
“True spoiling is nothing to do with what a child owns or with amount of attention he gets. he can have the major part of your income, living space and attention and not be spoiled, or he can have very little and be spoiled. It is not what he gets that is at issue. It is how and why he gets it. Spoiling is to do with the family balance of power.”
—Penelope Leach (20th century)
