A. what is the weight of the babies not to worry about the weight much if they're active and healthy otherwise also check if they are teething if so it could be due to that massage the calves temples and toes in the night with breast milk or coconut oil also give three meals in between snacks to them include all the seasonal fruits vegetables dairy products etc in their diet
