Girls, question about tummy. They prescribed us mamalac for prophylaxis as husband has lactose intolerance, and it's too early to do tests as said pediatrician. Who took it, what results? Maybe there are analogues? It's very inconvenient to use it :( And today we tried eспумизан л for the first time, how long should he help in theory?
