One Nanny I had made me lose my sim's child to social services and then came back for days afterward trying to pick up my sim's husband. I had a really good Nanny who worked hard but now the oldest child has aged up to a teen she calls to spend time with him, invites him to her house and out to parties etc and is generally flirty when he is around even though adults aren't supposed to interact with teens this way. so no more Nanny for that family
