How to plan a first birthday party without losing your weekend

A first birthday is a strange, lovely party. The guest of honour will not remember it, may sleep through half of it, and will almost certainly eat the cake with both hands. The party is really for the people who got you through the first year, and that is the best reason to keep it simple.

This is the plan we give friends: six weeks, a short list for each, and nothing that needs a whole weekend.

Six weeks out: decide the shape of the day

Before the theme, the balloons or the cake, decide three things. They make every later choice easy.

• Who is it for? Family only, family and close friends, or the whole baby group with their little ones. A guest list of 15 and a guest list of 50 are different parties.
• Where? Home is cheapest and easiest for naps. A park pavilion or a community room gives you space if the list is long.
• When? Plan around the baby, not the calendar. A party that starts straight after the morning nap, around 10:30 or 11, catches everyone at their best.

Keep it to two hours. Babies, toddlers and their parents run out of party at about the same time.

Five weeks out: the guest list and the invitation

Write the list in one sitting, with addresses or phone numbers next to each name. Then send the invitation early: four weeks' notice is kind to families with weekend plans, and grandparents who travel will thank you.

An online invitation earns its keep here. Guests reply in a tap, you see who is coming and how many children they are bringing, and reminders go out without you writing a single "just checking" message. If you want a starting point, our birthday designs open and play like a little film, and the birthday wording guide has lines you can copy.

Ask for the two things you will actually need: how many adults and how many children, and any allergies. Everything else can wait.

Four weeks out: the theme, kept small

A theme is a palette and one idea, not a costume budget. Pick a favourite book, an animal, a colour or simply "one". Then use it in three places only: the invitation, the cake and one corner of the room for photos. That is enough for every picture to look planned.

Three weeks out: food that survives a toddler

Plan food you can make the day before, or order in, and that is easy to eat standing up.

1. Something savoury and filling for the adults: sandwiches, wraps, a big pasta salad.
2. Soft finger food for small children: fruit, cheese cubes, mini muffins.
3. The cake, plus a smash cake for the baby if you like the photos.
4. Water, juice, coffee. Coffee matters more than you think at 11 am.

Two weeks out: the people who help

Ask two people for one job each. One handles photos in the first hour, while the light is good and the baby is awake. The other takes over the kitchen so you can say hello to everyone. Naming the job is what makes people say yes.

The week of the party

Check your replies and send a short note to anyone who has not answered. With an online invitation you will already know who those few people are. Buy the drinks, collect the cake, charge your phone, and lay out the clothes, the baby's spare outfit included.

On the day

Start relaxed: the first 20 minutes are arrivals. Do the cake around the halfway mark, before anyone gets tired. Sing, take the photo, let the baby make a mess. Then let the party wind down on its own.

Afterwards

Send a thank-you within a week, with one of the photos. If your invitation has a shared album, guests can add the pictures they took, and you will find angles of the day you never saw.

A first birthday does not need to be big to be memorable. It needs the right people in the room, a cake, and a host who is not too tired to enjoy it. Plan the shape early and the rest falls into place.
