Many twin and multiples parents worry that they’ll have trouble telling their newborn twins, triplets, or higher order multiples apart. Often times, even fraternal twins are hard to distinguish.
And yet, “identical twins” are not completely identical. There are many differences in appearance. Typically, one twin will be narrower in the face — the other rounder. Some identicals are even “mirror image” of each other.

The good news is that most parents quickly learn the subtle physical differences between their twins / multiples, and it is mostly friends and outside family that have difficulty.
Still, there are techniques to make it easier for everyone in your multiples’ lives to tell them apart. Having some of these techniques in place will be especially helpful when part-time caregivers come to your aid.
- Hospital wrist bands. Keep the hospital wrist bands on for a couple of days after returning home.
- Assigned colors. Assign a color to each of your twins, triplets, or higher order multiples.
- Dressing in assigned colors. Purchase clothing in the assigned colors and dress each accordingly. It can be fun to dress twins in matching outfits, differing by assigned color.
- Paint a toenail. An age old, tried and true method to tell newborn twins / multiples apart is to paint a toenail on one or more of the babies (in your chosen assigned color for each, of course). Why a toenail and not a fingernail? When the babies begin to suck their fingers, you can avoid ingestion of the polish.
- Color code your charts. If you keep charts for tracking feedings and sleep schedules, highlight each infant’s chart with their assigned color. (Check back for a future article on the subject of charting your infants’ schedules.)
- Color code your cribs. Choose bedding in the matching assigned colors, and place colored labels with their names over the cribs. If they share a crib, always place each infant under their name on either the left or right.

Tip: Take lots of pictures when your twins, triplets or higher order multiples are young, but be sure to label them to indicate who is who. Although you might easily tell them apart now, you might have more difficulty when you look back in a few years.

When our babies were young, we soon were easily able to tell them apart. We tried to take a lot of pictures, but didn’t always have time to go in and label the photos to identify who was who. Big mistake. Now that they are older, we look back at early pictures and often can’t tell them apart! At the time, we were easily able to key in on the differences, but looking back is more difficult. Often times, it is the color coding of the outfits in the pictures that lets us know.
Even with techniques in place, mix-ups can (and do!) happen. The trick is to be extra careful to check your charts and schedules and double-check which baby you’re holding. This can be critical in the case of food allergies, for example. One of our identical girls had a severe allergy to milk, the other not. A mix up did happen once, which resulted in our little sweetie vomiting after her feeding. Fortunately it worked out fine, but was pretty scary for a few hours.
How about you… what have you done to tell your newborn twins apart? Have you ever mixed them up?
