So my little man is now 12 week old. When he was born I he really struggled to keep anything down. We tried changing formula, anti reflux formula until the gp but him on a hydrolysed formula then eventually amino acid formula. We add carobel to this to thicken as it's really thin. Now he's with a dietitian who advised me to try reintroducing dairy as a lot of his symptoms are still there while not on dairy. I added 1 scoop to his bottles for 3 days and he seemed fussy and his poo was a little runny, however at the same time he had just had tongue tie cut. I originally thought it's clearly upset his tummy but now I'm questioning if they was the case at all or if his tongue was hurting him.He still has a cough and is snuffly which I thought was due to dairy but think it's due to acid reflux. I wonder if I should try again with dairy on maybe a comfort formula or something. He is not a huge fan of the amino acid formula and sometimes refused bottles making it super hard to feed him when we are out and about because he gets really worked up. Any experience or advice welcome thanks
