When choosing the best infant pajamas, it's important to consider safety standards and fit. If pajamas are too small, they can be binding and cause discomfort for the infant, but if they are too loose, they may be a safety hazard. It's better to purchase a few sets of quality, government-approved, brand name infant pajamas than have many different sleeping outfits that don't meet safety standards. In addition to those guidelines, picking different weights of cotton sleepers and baby pajamas to suit the season can help keep your infant sleeping comfortably.
Terry cloth and lightweight cotton are excellent infant pajama fabrics for warmer weather. Cotton fleece and brushed cotton, or flannel, are better choices in colder seasons. Blanket sleepers with a covered foot portion included can help keep your baby warm in winter weather. Yet, babies do tend to grow out of this type of sleeper quickly because of the foot portion, so you may want to choose warm, fleecy infant pajamas without that feature.
Instead, you can simply add socks to fleece pajamas that end at the ankles. Infants shouldn't wear socks in blanket sleepers with feet-covering portions already included. Look for a soft underside in the fleece fabric when choosing blanket sleeper types of infant pajamas.
Buying pajamas for infants at secondhand stores isn't recommended without the knowledge that the garments haven't been recalled due to faulty manufacturing. Buying new, packaged infant pajamas from reliable sources such as established stores that carry brand name manufacturers' baby products is a good idea to help guarantee quality. Always check labels and package information for assurance that the baby pajamas you buy are in keeping with any set government standards for infant sleepwear, such as flame resistance. Do your research before shopping and never be fooled by manufacturers who don't label the products as "sleepwear" but rather as "lounge wear" or another identifier as a way of getting out of having to comply with flame-resistant standards for pajamas.
Having fewer sets of top quality, safe baby pajamas is much better than choosing a large wardrobe of sleepers for your infant. Most likely, your baby will soon need a larger size anyway, and typically you're likely to find yourself washing your infant's laundry quite steadily. It can be a great idea to have at least one or two sets of infant pajamas in the next size your baby will need rather than too many in his or her current size.
