My new born is 19 days old. He is lactose intolerant and also had Rota Virus from which he has recovered. He is on Nestle nan lolac for the past 5 days due to low level of lactose. However since last night he has been profusely crying and his poop looked like pebbles and they were hard, without any blood on it. The entire night he cried painfully, we gave him 5 drops of Colic aid but that did not help much either. Please help as we are only panicking!!
