Touch that hurts, such as pinching a baby's cheeks, is not appropriate. Let the baby be in charge. Dressing the child as warmly or as lightly as you dress yourself is a convenient rule of thumb unless the infant gives clear signals that her thermostat is different from yours. Prompt attention to distress. Children should never cry for more than fifteen minutes without an adult reassuring them.
Some children are more tolerant than others of wet or dirty diapers.
This may depend on what type of diaper is used. Touching a child in a sexually stimulating way is always wrong. If you suspect abuse of any kind, find a way to protect your child. Get help if you need it. Report the abuser to the child protection service in your area.
