#asktheexpert My son is 1month 7 days old. His birth weight was 3.7 kg & now he is 5 kg. He is exclusively on breastfeeding. Actually sometimes he takes feed agressively & fast for 1-2 minutes & then starts coughing in between but he takes 5-10 minutes feed then fall asleep. When i try to make him burp refuses to sit on lap or up straight & becomes cranky. After few minutes spit out milk, sometimes its thick. I am very worried as he is not taking balance milk & also spitting my often
