Best 6-12 Month Pajamas

Candace Osmond

At 6-12 months, your baby is very busy and is definitely trying to crawl, walk, or just not sit still unless they are sleeping. You need pajamas that can let them rest but also double as clothes for play during the day in between naps. 6 to 12 months is a large timeline where babies are hitting a variety of milestones. If you’re selecting a 6-12 month size, look for options that have extra stretch that the baby can grow into.

What To Look For in 6-12 Month Pajamas

As you can see, there are many different styles of pajamas available online for 6-12 month old babies. 6 to 12 months can be a wide range in terms of sizes, so here are a few things to consider when purchasing comfortable pjs for your baby

Is Baby Crawling or Walking?

Your 6 to 12 month old is probably either crawling or walking. You want pajamas that move with your baby as they become more active. Pajamas with footies can be slippery for new walkers unless they have anti-skid on the bottom. 

The Material

Pajamas should fit snug and not loose. Most pajamas are made out of cotton or a polyester blend to fit snugly against your baby’s skin. If you want extra stretch, look for sets that include a percentage of spandex. That will give your baby some extra give as they move around. 

Also, be extra careful if your baby has skin allergies and look for hypoallergenic organic options. 

Thickness of the Fabric 

The season and the temperature will determine the type of thickness you need. You’ll want lightweight pajamas for hot months and fleece-like material in the winter months. Also, take into consideration that your baby may run hot or cold no matter what season it is. It’s best to have a variety of fabrics since the indoor temperatures can vary. 

Closures or Pull-Over Pajamas?

6-12 month old babies fall into a wide range of milestones. One thing for sure is that they are super busy and squirmy. There are different types of closures including zippers, snaps, and pull-over pajamas. The main thing you want is something easy to take on and off. 

Conclusion 

We hope that you are now more informed about what to look for and have an idea of what is going to work for your baby. Consider the material of the pajamas, the closure, safety features, the style, the sizing, how to wash them, and know your overall budget and how much you want to spend.

There is something for everyone on our list of the best 6 to 12 month pajamas that are sure to meet your needs. Take all of our tips into consideration so that you can make the best choice when shopping online.
