According to Dr Megan Rossi, founder of The Gut Health Doctor and SMART STRAINS, the key isn't trying to maintain the perfect routine while you're away. "Children's gut health thrives on consistency," says Dr Rossi. Rather than aiming for perfection, Dr Rossi recommends focusing on four simple habits. Dr Rossi says holidays are not the time to turn meals into a battle. While certain evidence-based probiotics may be appropriate in some situations, they should complement healthy habits rather than replace them.
