Wonder weeks are followed by ‘sunny weeks’ where the baby is much happier. When they find something in the new sensory experience that they feel comfortable with and interested in, they become happy again. The doctors behind the wonder weeks theory believe that the crankiness is because the baby gets initially surprised and shocked by each mental and sensory leap and is trying to figure the new experiences out. This may line with what many mums call ‘growth spurts’ when their normally lovely baby suddenly changes in attitude and habit for a few days before settling down again. It can also coincide with fussiness and crying, changes in appetite and interrupted sleep when the baby almost seems to regress before moving forward again. In the womb, the first sense that babies experience tends to be hearing, in that they respond to their mother’s voice and also to sudden loud noises.Īt birth, all of the other senses suddenly kick in and can be very exciting and overwhelming all at once.Īt each mental leap or wonder week, the baby learns to use their senses and perception in new ways, which gives them a push forward in ability. These leaps forward happen because of brain and nervous system changes at these times when the gorgeous little ones respond to new stimuli and broaden their sensory and perceptual levels of awareness at each time.

Their research found that babies tend to experience the same mental developmental leaps at ten specific times during their first 20 months.

This term was coined by Dutch doctors Frans Plooj and Dr Hetty van de Rijt and describes something actually quite wonderful. Īnd will they get here soon, because you could really use something wonderful right now. When you have made it through the labour and giving birth, and now have a newborn that seems to endlessly cry without sleeping or feeding patterns, and you feel like you couldn’t possibly suffer any more, you hear about.
