I am currently using Donnalix a pharmacy Medicine but it doesn't seem to be helping much as he is still settled during the day time sleeps and moving around alot during his feeds. He is currently on S26 Gold and on 180mls every 5hours. Could it be his formula or should i burp him longer then the first burp. An suggestion would be great medication wise or formula. Thank you
