Rachel Waddilove, who has looked after Paltrow's daughter, Apple, and son, Moses, claims giving a screaming child sweets can be the most effective way to halt disruptive outbursts, the Daily Mail reported Saturday.

"It is a case of 'needs must' when you are out, so don't feel guilty about buying a treat or some sweets to placate your child," Waddilove writes in her latest parenting guide, "The Toddler Book: How to Enjoy Your Growing Child."

"I don't think the No. 1 solution would be to give in to tantrums with sweets. But … if that's the only way you're going to get through the day, we'd never judge someone for doing that," said Carrie Longton, co-founder of the Mumsnet Web site for parents.
