Twins and Newborn Clothes

It’s an exciting time when a family welcomes two new babies into the world. But it can also be overwhelming trying to figure out what size clothes they need and how long they will last. However, understanding the timeline for newborn clothing can help provide peace of mind and give parents an idea of what to expect during this special period in their lives.

The truth is that all babies grow at different rates and there is no definitive answer as to how long twins will wear newborn clothing. Generally speaking, most twin babies tend to stay in newborn sizes for about 4-6 weeks depending on their individual growth rate and body type.

Average Weight of Newborn Twins

The average weight of newborn twins can be an interesting topic to explore, especially when it comes to how long they will wear newborn clothing. For the parents of these special babies in particular, this information can provide some guidance on when to shop for larger sizes.

A study conducted by the American Academy of Pediatrics (AAP) found that the average combined birth weight of a pair of twins is approximately 5 pounds, 8 ounces. When separated, twin babies tend to weigh closer to 5 and 6 pounds each. This means that both babies are likely in need of preemie clothing as well as newborn sizes.

However, even though the average weight for twins is slightly lower than singleton births, many twins born at full-term still weigh enough for regular-sized newborn clothes and diapers.

Do Newborn Twins Need Preemie Clothes?

The simple answer is yes, they do need them. Preemie clothes are specifically designed to fit babies who were born prematurely and can provide added comfort and protection for newborns who are smaller than average.

The length of time that newborn twins will wear preemie clothes varies depending on their size at birth and rate of growth. It’s important to keep in mind that all babies grow at different rates so it’s hard to predict when a baby should stop wearing preemie sizes. In general, most twins will be able to transition out of these garments within the first few weeks after birth as they quickly grow out of them due to their rapid development rate.
