My son was having loose motions but the reason was not confirmed as we normally don’t give him outside junk food to eat. He drinks only RO water and eats home cooked food. So we gave him antibiotics only for 3 days. Is it ok. He is complaining of stomach ache now but don’t have loose motions. We have stopped antibiotics and only giving drotin de syrup for stomach ache .should we give him more antibiotics
