My 3-month-old daughter used to sleep 3-4 hours straight at night, but now she wakes every hour—what could be the reason?

A sudden change in nighttime sleep patterns in 3-month-olds is a biologically-related and temporary developmental leap. During this period, brain development accelerates, sleep cycles begin to mature, and the baby enters lighter sleep more frequently. It's normal that they can't fall into deep sleep as quickly as before. Their bodies may also be going through a growth spurt, temporarily increasing nighttime feeding needs. Frequent waking at this age is usually a sign of a developmental leap rather than a medical issue like reflux, gas, or teething, and typically resolves on its own within 1-2 weeks. If your baby is younger than 3 months, unless there are signs like fever or breathing difficulty, it's not something that requires a doctor visit. Observing whether she calms down after 1-2 minutes when you wait rather than immediately picking her up supports her self-soothing skills.
