#asktheexpert my baby is 4 month old now. but suddenly his sleep has reduced. what to do

A. A sudden change in sleep patterns in a 4-month-old baby can be due to various factors, such as developmental milestones, growth spurts, or even teething. At this age, babies often experience a shift in their sleep cycle, with more active periods during the day and longer stretches of wakefulness. It's important to ensure your baby is comfortable and in a quiet, soothing environment. Stick to a consistent bedtime routine and avoid overstimulation before sleep. If the reduced sleep continues for several days, or if your baby seems unusually fussy or uncomfortable, it may be a good idea to consult your pediatrician to rule out any underlying issues.
