Food Allergies Treatment

What would you think is my son not tolerating milk and need soy?
Ok lets start off with hes not crying or having any symptoms other than the below stated…
With MILK, he drinks it, and wakes up every 4 hours wanting more bottle and crying. And takes a 30 minute nap all day
With Soy he drinks it and sleeps all night, and takes a 2 hour nap.
Im confused as to it being a allergy cuz he has no other symptoms than sleeping less. and waking crying.
BUT he refused to drink milk while hes awake and drinking from a sippy he taste it then trows it

I’ve had milk all my life but recently if I have ever had a smoothie with milk in or only sometimes if I have had a cup of tea and on other occasions the back of my tongue starts to swell up. What could this be because if I ever have cereal I dont get this???

My 21 month old has been throwing up lately, and it seems to be every time she drinks milk. She’s been drinking milk for 8 months with no problems at all, but now she’s vomiting alot. (No fever or other negative symptoms) Some suggested that it may be a lactose intolerance, but after researching that, it seems that the result would be diarrhea, not vomit. Others suggested an allergy to milk, but can a child suddenly become allergic to something that she’s previously had no problems with? We’re going to the doctor on Monday to be sure, but I’m, trying to ease my mind now! In the meantime, she’s drinking Silk soymilk with no problems. Thanks in advance:)
