A. Hello my dear parent! Child’s feeding and sleeping pattern keeps changing in the first few months after birth. This is a phase of growth. As long as there is no visible discomfort in the child, nothing to worry. Continue to exclusively breastfeed your baby on demand. Consult your doctor for further guidance.
