Can too much milk in a 3 yr cause stomach cramps?

Possibly: If your 3 yr old is getting stomachaches after drinking milk, the most likely cause is lactose intolerance . Try a soy or almond milk. If the problem continues, consult your pediatrician.

Yes: Good question. Too much of almost anything can cause upset stomach, stomach cramps or other GI issues. In addition, a balanced diet is an important way to provide all of the nutrients our bodies need, which is important for everyone, and especially a growing child.
