My 16 week old boy has GERD and has struggled to feed since day 1. We have recently been discharged from the faltering growth clinic as he has began to put on weight slowly now he is medicated. However, everything I read says he should be drinking at least 900ml in 24 hours and I can barely get 700ml into him. How much did your babies drink at this age? I'm wondering whether I'm becoming to obsessed with the amounts.
