When masturbation occurs outside of her bedroom, first try distracting her. Try distracting her with an activity preferably requiring the use of her hands. If this fails, discipline her reminding her that you know it feels good, but she can't do that in front of other people. Before the age of four or five she may need to be sent to her room. Discuss how you are handling this with all her caretakers.
Consistency is key to success.
Call your physician if you suspect that your child has been taught masturbation by someone else, your child tries to masturbate others, your child continues to masturbate in front of others. Marci, masturbation does not cause physical injury or harm to the body, promiscuity, or sexual deviance. Your child is normal. Masturbation is not abnormal or excessive unless it is deliberately done in public places after the age of five or six. Watch this if baby's meals end with thrown food.
