HELP! 15 kids will come to DS Party and it will rain

[Frozendinonuggets]

I want to hide in the bathroom and cry.

How do i entertain 15 kids aged 5 to 7 in my living room? Any idea or positive feedback (like "you can do it!) is welcomed.

I know it sounds stupid but I am really afraid it will be a f* disaster.

Long story short. My son will turn 6 and he will have an afternoon Birthday Party in few days.
We said max 8 kids. He wanted to invite more, but we said to him that he could invite more kids only in case someone cannot come.
Well, we sent the invite few weeks ago and many said they cannot make it and few did not reply. So he invited few more as agreed. In the last couple of days ALL the people that said could not come changed their mind. And a couple are bringing sibling.

And it will rain.

HELP! 😅

I used to teach this age group and as a result ran my DCs’ parties with military precision like it was a classroom! I divided the time up into sections, eg
0-15 minutes - quiet craft activity for children to do as they start to arrive.
15 - 60 minutes - games. All planned in advance. Musical statues, musical bumps, that one where you have to roll a six and start cutting up chocolate etc.
In between each game I would sit everyone down and say I would explain the rules once everyone was quiet.
60 minutes - food. Eating in the kitchen but encouraged to go into the living room where a film was playing as soon as they had finished. Regroup for cake and singing.
And then just sitting quietly watching the film until collected.
Two hours is the absolute maximum. You could probably get away with an hour and a half.

One of the 'best ' parties my DC had was the one where (much like pp suggestion) we covered furniture and floor in blankets, had food in paper bags and put Frozen on the TV.

Ice cream station - give each child a scoop of cheap vanilla ice cream in a dish (plastic ikea bowl or paper ice cream cup). Set up bowls of sprinkles / mini marshmallows / popping candy / mini smarties etc., a few sauces and some squirty cream for the kids to make ice cream sundaes. Pinch pick up some of those little wooden spoons from the 'lunch to go' sections of M&S or Tesco.
You can do the same with cupcakes - buy plain fairy cakes from supermarket. Put out some icing tubes and sweeties / sprinkles for decorations.

I was coming on to pretty much say exactly this.

I used to have big parties for my older 2 in my small flat mostly due to costs.

Break up the 2 hours as above.

A mixture of welcoming and opening gifts (if you are doing that then - I always did) , saying hi to each other and people arriving, adults chatting or leaving etc.

Then corralling them in to a few organised game (with free play in between to eek the time out).

Sit down, even on the floor with a picnic blanket if no separate kitchen with table.

And yes, then a film to watch and/or free play.

Then time for cake and happy birthday, more free play then home.

Clear your room as much as you can, expect a level of mess and chaos for 2 hours. Then collapse in a heap after.
