Talk to Pediatrician on Fever, Stool

Assalam o alaikum. My son is 10 months old and is teething currently. Yesterday he developed fever and was extremely fussy for which I gave him Dolor and he’s better ever since. Along with the fever, his poop consistency and frequency changed too. He usually poops once a day but since yesterday he’s pooping 4 to 5 times a day. Poop is grainy and has mucus in it. The colour is sometimes yellow, sometimes greenish yellow. He’s active, acting normal, but not eating as such. Usually he eats solids happily but right now he’s mainly depending on formula. Please suggest if the situation is alarming and what should be done? I’ll be grateful.
