At different times - in different ways. There were birthday parties and at home. Important role in choosing a site is time of year, even though winter can be go on nature and the snow fry station. At my son's birthday in March, when we have raging storms (such is the nature of ), so it marked the birthdays while at home or we go with him to a restaurant (by day, of course), and then to the shops to choose gifts. In summer you can do so at sea if the sea nearby. That file on the table if birthday is celebrated at home, then start preparing for this event need at least a week: make a menu based on the him to procure all necessary foods and beverages, order a cake, unless you are going to bake it yourself. This training will greatly improve mental health on the eve of the holiday.
The literate housewife for 2 days before events begin to cook: cook vegetables for salads, make snacks, which are stored in a refrigerator (all sorts of sharp carrot salad, ferns, etc.). Perhaps the hottest days: the day before and the day immediately celebration. On the eve of being made salads such as Russian salad, pate, seafood salad, aspic, aspic, baked cakes. On the birthday of preparing hot dishes, cut vegetable salad, cut the sausage and cheese. Is not it true tedious procedure, and costs very expensive. Therefore, the perpetrators (especially the culprit 🙂 celebration) is not recommended to take part in all these preparations.
