A. If your child has difficulty swallowing food or liquids, it's most likely because of a sore throat. Or your child might have a sore throat because of a cold, glandular fever, mouth infection or mouth ulcers. Babies can have difficulty swallowing if they have a cold that's causing a blocked nose.
