So today I was at a restaurant and my 15 month old dd was being awful! So I gave her a few sips of my diet Dr pepper, she has never had soda before, ever! So then she really liked it and freaked out even more if I did not give to her! She had about a cup total. So my question is... Tonight she was really hyper,fussy and gassy and just plain irritated! Could it be the soda? I will never give her soda again!
YES, it most likely is the soda. Carbonated beverages are known to cause gas pains in the stomach, especially such a small stomach that consumed so much. Not to mention that the caffeine and artificial sweetner is most likely the cause of the hyperness and fussiness. I'm guessing that she also has a headache to go along with the tummy ache.
