These are arguably the easiest parties to get right! If your kids are very young, you can often buy party supplies that are just fun and colorful. Celebrating the first birthday of a child is as much a party for you, friends and family as it is for the child - and is a great way of getting everyone together. First birthday themed party supplies are a must have and are available in blue for the birthday boy and pink for the girl and feature the number 1, of course! Banners, badges, balloons and a whole host of other party supplies are available to help everyone celebrate - even a number 1 pi. Of course, the birthday boy or girl will be too young to break it, so it's up to you and your friends and family to have fun on their behalf!
