my baby is 2 months old and went from a very content infant to crying before after and during each one of his feedings. He is not spitting up but seems very gassy. He just went for his immunizations and was fine at the time of the visit 4 days ago but now is a total different infant. He continues to sleep through the night but during the daylight hours seems to do nothing but cry a "pain cry". He is moving his bowels regularly and eats approx. 5 ounces every 2-3 hrs. Do you thing he could have a milk allergy?

Optional Information:
Male , Age: 9 weeks

Already Tried:
rocking, making sure diapers are changed, burping, mylacon drops, tylenol after immunizations 4 days ago.
