DD will be 1 next week. I've noticed in the past week when she has dairy (yogurt or cheese) she has become super fussy the next day and I can hear her stomach making gurgling noises. Her next poop is usually diarrhea or very loose. She also gets very fussy and screams making it hard to comfort her. She has had yogurt and cheese before and was fine, this has just happened in the past week.

Could this be a milk allergy or lactose intolerant?
She has her 12m visit Friday so I will discuss with ped then, just looking to see if anyone has a similar issue.

She is ff and has been on gentlease since I stopped bf at 2m. Not sure if that mattera.
