Baby is of 79 days and on breastmilk plus formula milk. He used to take 60ml every 2 hours and sometimes 90ml once or twice in a day. We shifted recently to our native where there are lot of people. Now he is not feeding well. Sometimes taking 60 ml every 2 hours or 30ml and push out the bottle nipple. At night taking only 30 ml every 2 hours. Taking80-90 ml once a day. Now a days sleeping a lot but active when not sleeping. Passing stool everyday and passing good amount of urine. Is this change in feed due to distraction or sudden environment change? Please help.
