Pulling my son from care

Er

So this is my son's first week at daycare. Typically durring the time he's there he should eat 12oz. He's only being given 10. The first day I excused it as him being new. After the second day of watching him being super hungry at home (chocking on his bottles he's trying to drink so fast) I said something to his teacher and sent him more than enough to eat in smaller bottles. Told them to do what they needed for him to eat enough. I even checked in on my break to make sure he was good each day. I work at the center and live pretty close so it's not hard for me to get him anything he may need. His PT saw him eat his bottle yesterday and her face showed concern for the way he was eating. And to make it worse they ignored his care plan for reflux and laid him down right after his bottle and he spit up all over himself. So, today my husband called off and is keeping him home. We want him out of the room, but I'm not sure if I'm over reacting since he's still pretty new there.
