To not have a clue what to do for first birthday

[Lindah1]

Dd is 1 this summer. I've never been to a first birthday party so have no idea what people expect. It would be about 7 sets of parents plus kids all around the one year mark. Would you invite adults without children, or would that look grabby? No family nearby.
Thinking of having something at home, cold buffet for adults,snacks, wine, beer, soft drinks, would you lay on food for the kids too or just let them have the run of the freezer foods?
Entertainment wise just thinking of getting out the toys maybe buy a ball pool, do you think people would expect more??
Many thanks

We just had a little get together, grandparents, aunts, uncles and a couple of close friends. Kids invited. Everyone fed the same buffet food. Couple of hours, bubbles and drinks (for adults), sing happy birthday and cake then send them on their way ha ha

Honestly, that sounds a lot for a first birthday. They won’t enjoy it so it’s all about how you feel and how much you enjoy it.
We did soft play/safari park with a meal out somewhere child friendly for first (and second, and third) and then parties from 4, when they can really get excited and when the party is about their enjoyment, not the parents.
That’s not to say you shouldn’t! People won’t expect much at all so just do whatever you will find fun for yourself (while baby naps in the house ;))
