10 week old doesn’t like the taste of formula...

My son is 10 weeks old and he’s been drinking formula since birth. He’s gone thru 2 different formulas bc he’s allergic to milk based formula and he’s been on an amino based formula for about a month now, with no problems. Recently, he’s started fussing during every feeding, giving me trouble to drink his normal 3-4oz per feed. He seems to only tolerate about 2oz per feed before just no longer wanting the milk at all. I’m thinking it may be a taste issue, if possible.

Anyone else experiencing their baby not liking the formula taste? Am I going crazy?!
