Hello doctor my baby is 19 month old. He sleeps a lot. Is there any problem with him? He sleeps 14/15 hours in a day

A. Hai good evening !! Sleeping 14-18 hours a day in infants is normal ,some might change sleep pattern reduce day nap due to playing while few take naps in day time too. Check if baby is active,achieving milestones good at gross,fine motor skills or not,if so no need to worry,sleeping soundly is good helps in growth harmone
