My kid is sick

Have no idea where to put this.

So this morning my son woke up wanting a drink and he ended up drinking 4 oz of water maybe little more but he threw it up and hasn't stopped...he complained that he was hungry and I gave him toast knowing I shouldn't but he threw it up. My husband keeps trying to feed him gave him apple sauce and he eventually threw that up...he has no temp forhead one says 96.3 and the armpit one says 97.3 he's ghost white including his lips...i keep trying to put Gatorade in him. All his pukes have been clear with maybe some kind of clear mucous other than the bread and apple sauce...didn't see the Gatorade come up. He's had 4 pukes in 4 hrs and my husband says we have to push food on him he has to eat something but I know from my visits with my sons doctors not to do that...that the first day be liquid but he's acting like I'm stupid like I don't know he needs to eat but he's not listening to the fact that for several times now the doctor has told us every time I go get him check to only do liquids first...i have problems with anxiety so to see my kid like this gets to me to the point of crying and my husband just makes it worse...my kids only 4 will this anxiety while their sick get any better?

EDIT: Thank you for your help. After my husband saw he was puking up the toast and applesauce he stopped and we gave him Gatorade...he slept a few hours and his color came back and wanted to eat so we tried apple sauce and waited 45 minutes and gave him some more. He's kept it down so I'm hoping that's that. Just wish my husband had listened to me.
