Would be nice to have for those of us parents like myself who have twins. Twins are hard enough to prepare for, then you have to find party ideas that will work for two children of the same age, birthdate, and eye and hair color. Noah's Ark could have two-by-two party hats with the ark and the animals unloading. Noah's Ark could have cake toppers that include two of a set of animals, and have two individual numbered candles. Or numbered candles that are being held by twins(one on each side). Noah's Ark could have balloons with the ark scene on them and have "happy birthday". Thank You for your time and I hope my idea is a help to you in making future party ideas. Just remember, some families get more than one child at a time.
