If you want to be at peace on the day of the birthday tea party, plan it 6 – 8 weeks in advance. It'll give you enough time to purchase and mail the party invitations and to make travel plans, if needed. If you have less time, don't panic. Just a little careful planning and every thing will be set. Of course, if you want to increase the number of guests attending the tea party, it is advisable to plan everything in advance.A tea party can be held for various reasons, not necessarily just for a birthday. The reasons may be to teach your child etiquette and manners or to discuss any important subject. 'Little beauties' love wearing beautiful dresses and getting all the attention. What they also love is acting 'grown up'. They are delighted at the sight of cakes, fancy cookies, sandwiches, games, etc.
