This is one of the most frequently asked questions you may ask as a brand-new parent/caregiver. Our research on the leaps, which began in Tanzania in 1971, led us to discover that all babies from time to time cry more, and are more cranky and clingy than normal. Periods when babies can be inconsolable and when parents cannot figure out what is wrong.

[1] (literal translation: Ai, I'm growing!) by physical anthropologist Hetty van de Rijt and ethologist and developmental psychologist Frans Plooij. Originally published in 1992, it has been republished several times, with an updated 6th edition published in 2019. [2] Drawing on many years of observation and analysis of infant development, it gives parents practical guidance to help their baby's cognitive development through its predictable stages or 'leaps'. Its theoretical basis is Perceptual Control Theory, which predicts and explains the observed phenomena. Questioning of the research with mother-infant dyads has received some attention in the press and social media, though sometimes reducing it to a matter of sleep schedules. [3] The research has been replicated several times, and Brazelton found it to be mutually confirmatory with his own work. The book continues to be popular, and the publisher has produced a mobile app based on the book. [4] Claims [ edit ]
