Hi Melinda

You are right fluid is more important than food. If jacob will only drink milk then give him milk. One trich you could try to cool him down is if hes a favorite soft toy, open the seam and but some ice in a plastic bag then put this inside the soft toy, tell him that the tou is cold and needs cuddles. ( sorry I dont know how old Jacob is) But I'm sure that you could perhaps find some way to let him know that the toy needs cuddles.
