Irritable Bowel Syndrome Treatment

My 18 month old daughter has an ear infection (likely caused by a milk intolerance) and we’ve been advised to treat her with antibiotics, homeopathics and arabinogalactans. We’ve asked if this is safe to take together and our naturopath says yes. However, we’re just looking for a little support on this from knowledgeable people. PS We’re also using probiotics which we have no problem with. Thanks!
