7 month old barely eating

Kendra • First time mom to my baby boy, 06.04.19 💙

I’ve posted about this before but it seems to be getting worse, my 7 month old will barely eat anything, for over 2 weeks now he is no longer interested in having baby food, he only wants rice cereal (which I’m trying not to give him too much of but it’s hard when it’s the only thing he will eat). And now as of yesterday he’s barely drinking his formula, he’s maybe had about 15 ounces in the past 24 hours. He is teething pretty bad and I think it’s causing him to lose his appetite.

I don’t know what to do at this point, should I contact his doctor?
