#AskTheExpert hello mam, when baby recognise sound? My son is 3 month old

So After completing the age of three months or 3 1/2 months a child has its vision the child learns to respond to the sounds that are happening around the child you know like whistling clapping all these things apart from that a child would give a smile to you sometime because after the age of 3 to 3 1/2 month a child learns to see is well so they start recognising people as well
