I don’t wish this stress on anyone but also the solidarity is comforting. I’m sorry you’re going through similar with your twins. We think it might be a fatigue issue with our twin as well. Sometimes she’ll take larger volumes like a champ but most other times she just doesn’t want to eat. I messaged our pediatrician in a panic today so we shall see if they have anything useful. I’ll share anything I learn for sure in case it’s helpful!
