7.5 month old grandson sudden started fighting drinking his formula bottles and then started refusing to eat baby foods too. Occasion low grade fever. Doctor appointment last week confirmed no ear problems, possible teething but no teeth yet and still refuses to eat anything. Now foul smelling diarrhea as well. Will not eat baby food or table food and only 3-4 ounces of formula 2-3 times a day. Has also thrown up twice. Used to take Tylenol with no issues now have to literally force it in him, taking two of us to get him to take it without spitting it out. Only other change is brand of formula, from similar to Costco store brand and now back to similar. Can this still be teething? How long can he go with decreased amounts of formula without it affecting his growth and development?
Babies start to become fussy about food around 7-8 months of age and their appetite also swings back and forth. These not-wanting-to-eat phases do not last for long. Do not force-feed the child and try to bring some variety in his diet. Foul smelling diarrhea indicated some infection for which you need to consult your Pediatrician and give the child plenty of water. Teething issues come up repeatedly whenever new teeth erupt, but they can cause irritation but not loss of appetite.
