my teenager (17) is really mean to my (5) year old out of jealousy or what not . anyway my toddler doesnt understand this . I tell my toddler that it isnt him it is my teen that is kinda wierd right now and i tell my toddler dont worry mommy loves you . now , my toddler was practicing his full name and named us all first and last names . my teen has a different last name but i did not tell my toddler this . my husband says that it is better to leave it alone and not tell my toddler that his older brother is a half brother and has a different last name .
I just was wondering ... when is the appropriate age to tell a child that a sibling is a half brother ?
