There is a great deal of advice about hosting a children’s party and almost none about attending one. Which is odd, because most parents go to twenty parties for every one they throw.
None of it is complicated. It is mostly a handful of small things that make a host’s afternoon easier and cost you nothing.
Reply, and reply properly
This is the whole of it, really. The single most useful thing a guest does is answer the invitation by the date on it.
Numbers determine the food, the room and often the price. A host chasing six non-responders three days before is a host who cannot confirm anything, and every one of those messages is someone deciding whether to cater for a child who may not come.
If you are not sure, say so with a date attached: “probably yes, I will confirm by Thursday.” That is enormously more useful than silence, and it takes the same ten seconds.

What to bring
Whatever the invitation says. If it says no presents, believe it; if it names something specific, do that. Vague guidance means the host does not mind, and in that case something small and specific beats something large and generic.
Books are the safe answer at almost every age and nobody has ever minded receiving one. If you are buying a toy, it is worth a thought for the parent carrying it home — anything with a hundred small parts or a loud permanent noise is a gift to the child and a problem for the household.
Keep the receipt or the gift receipt in the bag. Duplicates happen at every party and it saves an awkward conversation.

Arrive on time, and leave on time
Both ends matter and the second one matters more than people think.
The first ten minutes are the most chaotic part of any children’s party, and a guest arriving twenty minutes late walks into the middle of an activity that has already started. Turning up within a few minutes of the stated time makes it much easier to run.
The finish time is usually a real constraint rather than a suggestion. Most venues are booked by the hour and most hosts are watching the clock while being too polite to say so. When the party is over, gather your child and go — the parent who lingers for another half hour is the reason a host is paying for extra time.

If you are staying
Under five you almost certainly are, and there is a version of staying that helps and a version that does not. Our guide to whether parents should stay covers when the question arises at all.
What actually helps
- Watch your own child. The host cannot supervise ten children and run the party.
- Say hello to the host early, so they know who arrived.
- Talk to the other parents, particularly the one standing alone.
- Take a plate, or stack a few chairs at the end without making a performance of it.
- Do not manage the running order. Suggestions about timing are rarely wanted.
- Keep your phone down for most of it.

Tell them about allergies before the day
If your child has an allergy or a dietary need, say so when you reply rather than at the door. A host told a week in advance can plan; a host told on the doorstep is standing next to a table of food they have already bought.
Be specific and be plain about how serious it is, and offer to send your child with their own food if that is simpler. Most hosts are relieved rather than offended by that offer.
The same applies to anything else worth knowing: a child who finds noise very hard, one who will not eat in front of people, one who may need to leave early. Understood’s resources for parents cover the wider version of this, and the practical principle is the same — a host who knows in advance can usually accommodate something easily.

The awkward moments
Your child does not want to join in. Fine. Sit at the edge with them and let it be. Our guide to calmer parties works as a guest’s checklist too.
Your child is having a hard time. Take them out of the room briefly rather than managing it in front of everyone. Nobody minds, and everybody has been there.
You need to leave early. Tell the host when you arrive, not as you slip out. It matters for the cake timing.
Something gets broken. Say so immediately and offer to sort it. It is always smaller than the silence about it.
There are no party bags. There is no need for there to be. Our guide to party bags explains why plenty of hosts skip them.
Being the parent of the child who is difficult that day
At some point it is your child who hits someone, refuses to sit down, cries through the singing or will not hand back a toy. It happens to everyone and it is worth knowing what actually reads well in the room.
Move in calmly and deal with your own child rather than performing a telling-off for the benefit of the other adults. Apologise once, briefly, to whoever needs it, and then stop — a long apology makes the moment bigger than it was. If it is not settling, take them out for five minutes rather than trying to fix it in front of an audience.
What other parents notice is whether you responded, not whether you produced a flawless intervention. Almost all of them have had the same afternoon within the last year.

Afterwards
A short message that evening is worth more than a card a week later. One line saying they had a good time, ideally with one specific detail, is genuinely the nicest thing a host receives after a day of running about.
Get your child to say thank you to the host directly before you leave, too. At three that is a prompted mumble and it still counts — it is the practice that matters, not the delivery.

Frequently asked questions
What is the most important thing a party guest can do?
Reply by the date on the invitation. Numbers determine food, room and cost, and a host chasing non-responders three days before cannot confirm anything.
What should I buy for a children’s birthday party?
Whatever the invitation asks for. Where it is vague, something small and specific beats something large and generic — books are safe at almost any age. Keep the gift receipt, because duplicates happen.
When should we arrive and leave?
Within a few minutes of the stated start, and promptly at the finish. Most venues are booked by the hour and a lingering guest is why a host pays for extra time.
When should I mention an allergy?
When you reply, not at the door. A host told a week ahead can plan; one told on the doorstep is standing beside food already bought. Offering to send your own food is usually welcomed.
What if my child will not join in?
Sit at the edge with them and let it be. Take them out of the room briefly if they are having a hard time. Nobody minds, and every parent in the room has been there.
