Agree with remission and seeking second opinions. Will say my son like ensure plus (extra protein) versus pediasure. So cheaper, tastes better and higher calories. 'Gain weight' is such a band aid situation when she needs remission. Also, does she want to eat? Does she like certain foods? Literally ensure plus with nut butter smoothie, like a milk shake? I just don't get how some people think we can just force feed a toddler. They eat when they are hungry, and I swear at times mine lived on air BUT I did super high calorie stuff when they would eat. Maybe adding digestive enzymes? Keep us updated on your wee one.
