When I was young there was this advert on TV that featured a man, his wife and a toddler daughter. The advert was either about a shaving cream or a shaving gadget.
It was set in the girl's bedroom, very early in the morning and the mother would appear fully dressed and ready to leave for work. When she gave the girl, still half asleep, a peck on the cheek, the girl would say "Bye Mummy".
