What it is
A first birthday is more for the grown-ups, but the star is the baby. Keep it short and around nap time, with a smash cake for the classic photos, a play corner for babies and good food for adults.
Plan ahead
- Three weeks before: pick a time that fits the baby’s routine (often after a morning nap).
- Two weeks before: print a photo from each month of the first year for a “12 months” banner.
- The day before: bake or order a small smash cake (6 inches is plenty) and a main cake.
Set the scene
A “ONE” balloon, the monthly photo banner, a decorated high chair and a soft play mat area. Keep decorations out of baby’s reach.
Activities
Time capsule
Guests write a message to be opened on the child’s 18th birthday. Add the day’s newspaper and a photo.
Smash cake
Strip the baby to a nappy or a cake-smash outfit, put them on a wipe-clean mat, and let them dig in. Have a warm bath ready afterwards.
Sensory play
Soft blocks, a small ball pit, crinkle books and musical toys for the babies and toddlers.
Food and drink
- Grazing platters, sandwiches and dips for adults
- Soft finger foods for little ones: banana, steamed veg, rice cakes
- Tea, coffee and fizz
Tips
- Use a simple sponge with a light cream frosting for the smash cake; avoid nuts, honey and very sugary icing for babies.
- Keep it to two hours - a tired one-year-old is not a party guest.
On the day
- Arrival (20 min): guests write a note for the baby's time capsule or a wish card.
- Food and mingling (30 min).
- Sensory play corner (open throughout): soft blocks, a ball pit and board books for the babies.
