"When parents are away, we save the day," is an excellent example of a catchy rhyming babysitting slogan. "I keep your kids in sight when you're out for the night, so things turn out right!" is also a great slogan.
"When you're in a rush, in (insert babysitter name here) you can trust!" is another good babysitting slogan. It is smart to incorporate the babysitter's name or the babysitting company name within the rhyming slogan, for a personalized effect. When parents choose sitters, their biggest concern is their child's safety, so using words like "safe," "kind," or "heart" is a great idea.
