First birthday balloons make baby's first big day special, with a giant '1' foil, 'One' script and soft pastel or bright primary latex. Match them to your first birthday party supplies, add a name with personalised balloons, or shop by age across our children's age balloons in the wider balloons range. A giant '1' behind the highchair is the classic cake-smash backdrop, air-fill it so it stands steady for the photos rather than bobbing on the ceiling.
