6 1/2 months. I switch his formula last night because thats what I have on hand. He took 5oz of it. His last feed was 3:30am. Usually he eats 6am and 9am. But he does not wanna take his bottle whatever tricks I do. First time this happened. Today I found his formula and tried to feed him and he refuses the bottle. He is teething. His other two teeth from top is coming out, he looks normal and playful. Should I call Pedia? He is not on solids yet. I’m worried.
