Given the above summary, write a detailed text in English for it.
What you really don't want to be doing is flying around a few hours before the party trying to get food and decorations and goodies all sorted out. You also want to make sure that you know who is coming to the party, so you want invitations to go out at least a few weeks in advance.  Make a list of the food you're going to have, the decorations and games you're going to need, what your budget is. This way you won't be caught by surprise when the party suddenly rolls around. Have a people limit. Make it clear to the parents of the kids who are coming whether siblings are allowed, what the age group is going to be, and whether or not they need to stick around with their child (the answer to that is yes, yes they do). Some people will ignore your request, but at least it will be out there and will make the more polite parents do as they are asked. Make sure that your family knows what they need to do to help you out. Do not attempt to run a children's party all on your own. You will end up exhausted and worn out, no matter what, but having people to help with things like set-up and clean-up and the games can make everything 100 times easier.  Ask family members or close friends to lend a hand with the party (especially if they've got a kid coming to it). It can be something as simple as bringing over some food, helping put up decorations, or even pick up the cake if it's a birthday party and you can't. Have your kid help you make the invitations and the decorations. This can be a fun process for both of you. It will lend a kid's touch to the proceedings, which is really what it's all about, right? If you don't do this, there are going to be meltdowns from the children and you'll end up as a de facto babysitter for some of the kids who aren't yours. By having a specific time that you start and end, you'll make sure that people get their kids out of the way before all the tantrums start.  If your child is at the age where they're still napping, make sure that you don't schedule the party right during nap-time....
