Most childhood illnesses are common, short-lived and nothing to worry about, though a few need closer attention. Chickenpox causes an itchy, spotty rash and usually clears up on its own within a week or two. Measles and mumps are less common thanks to MMR vaccination, but can still occur and are highly contagious, so it's worth keeping vaccinations up to date. Colic — persistent crying in an otherwise healthy baby — is common in the first few months and usually resolves by around four to six months old.
Trust your instincts as a parent: if a child seems seriously unwell, has a high fever that won't come down, is unusually floppy or hard to wake, has breathing difficulties, or you're simply worried, contact your GP, NHS 111, or in an emergency, go to A&E or call 999.
