Can sleep affect baby intelligence myth

Many parents also notice that a well-rested baby seems more alert, more […]

Why newborn wakes up frequently

Parents therefore may notice only some arousals, and reported waking frequency can […]

What a 3-month routine can realistically look like At this age, infants commonly move through repeated cycles of feeding, brief interaction, and sleep. Sleep may still occur in several short sessions, and longer, more consolidated nighttime sleep often develops gradually rather than suddenly. Research on infant and toddler sleep patterns supports keeping expectations flexible during […]
