2 month old baby last 2 days suddenly not responding to my call, its responding light visual ratals and social activities. kindly please suggest

A. It’s completely normal please do not get worried about it in this age kids don’t have clear vision and they don’t necessarily respond to your sound all the time it’s alright if the child is not giving a response and if you were thinking the child was responding previously that is completely alright after three months completing then when the child will gain its vision you will see everything happening and falling into place as per your expectation within the age of 3 to 9 months
