The Mothers of Multiples Society is a great organization for parents expecting (or already arrived!) twins, triplets or more. It has an amazing support system and provides endless resources to parents with multiples. Meet with other parents experiencing the same issues you are facing. The also host an amazing semi-annual children's clothing sale that gives members an opportunity to purchase gently-used clothing, baby furniture, toys, etc. that other members are selling before the public can! This provides members an opportunity to ease the financial burden that many parents of multiples experience. Several friends are members and I've had the pleasure of attending their semi-annual clothing sale for the last 8 years and have met other members who have benefited from the amazing support my own friends have experienced.
