Hi all, my 5 month old son suddenly started diarrhoea one day and went 8 times that day. No fever or vomiting but gp said it was gastro. I feed bm and formula due to low supply. For a couple of days we ended up feeding rice water and breastmilk only and the diarrhoea started clearing up. Then we slowly introduced normal formula and diarrhoea came back but only 3-4 times a day. After 1 week ds was losing weight probably cos of rice water so we were told to stop rice water and move onto lactose free formula and wait for gut to heal. Now after 2.5 days on lactose free his diarrhoea is getting way worse - 6 times a day at least. How long did it take for your baby's stools to become normal again after using lactose free?
