Twins, Triplets & More Support Group
Triplets & More","This community connects people seeking information and experiences about multiple births. Different names for multiple birth are used, depending on the actual multiple. Common multiples are two and three, known as twins and triplets respectively. Share your thoughts and find whatever support you need."
The reason I would think you'd want a triplet stroller is because when the twins are a or even 2 years, your older child will be 3 or 4 and you won't be needing a stroller as much for him, but you WILL need three seats for your triplets. At that point two doubles will be excessive.
