I understand your feeling
And also I appreciate your concern towards your baby.
I would like to tell you something babies cry first. Babies express their uncomfortability with their intensity of cry. According to you your baby's having stomach pain. If so there would be flexing of hip joints and hands will be away from the body and the body will be stiffened and cry will shrilled he/ she will be having fever, constipation or loose motions. You just need to consult a child specialist for your assistance and anyone will do. If not try symethicon drops before consulting any.
