How many cups of milk does your one year old drink?
Also, can it take awhile to develop an allergy? Ive noticed every time my girl eats cheese she gets diarrhea. But never has before.
Maybe she is lactose? Have you had it checked? Allergies can come at any time.
Mine drinks about 18-27oz of milk daily, She also eats a lot and drinks about 3-4 (her sippy cups) cups of water.
My daughter drinks soy milk and her pedi told me two cups a day. Idk if it’s different for other milks.
Also, there’s lactose intolerance, lactose malabsorption, and milk allergy. It could be either of those or neither.
