Dear scorp 2003 I am sorry to hear your baby is ill. I think yur baby has got secondary lactose intolarence.
This is a condition which quite commonly happens in infants. The intestine which got some special enzymes
which break down milk sugar lactose to glucose
. Infetion may damage those enzymic floora as a result
the milk sugar can not convert in to glucose so diarrhoea
persists. I think you put the baby on lactose free milk, take the baby to your doctor who may send the stool for culture and sensitivity and give adequate treatment if infection is found. I wish your child speedy recovery. Kindest regards S.K.Mukherjee
