It seems that your baby's original problem was typical colic.Another possibility at first was lactose intolerance but he did not improve on a soya formula. What is unusual is that his colic has persisted and he is now 5 months old.Colic normally does not last for longer than 3 months. Perhaps the fact that he is a premature infant is the reason that it has gone on for so long. It would be advisable to put your baby on an anti-colic formula such as Novalac AC.
