My baby has frequent stools in a day, mostly after every feeding. It's like he passes stool almost 10-15 times in small quantities. He does not burp after feeding instead passes the gas through down. With every passage of gas his poop also goes. Stool is semi solid with water. Full term baby. His weight also increasing in slow rate. Now he just reached his birth weight after initial fall. He is 20 days old. Frequent loose stools could be the reason??
