Transitioning Sleepwear Needs from Infants to Toddlers

Transitioning your child’s sleepwear from infant to toddler can be a delicate process. As your little one grows, their sleep needs change, and so does their comfort level in different types of sleepwear. 

When your baby is an infant, sleepwear is all about keeping them snug and secure. You probably started with sleep sacks and swaddles to mimic the comfort of the womb. 

But as your baby grows and becomes more mobile, these options can become restrictive. That’s when it’s time to think about transitioning to toddler sleepwear.

In this guide, we’ll cover everything from recognizing the signs that your baby is ready for a change to choosing the best sleepwear for toddlers.

5 Steps to a Good Toddler Bedtime Routine

What is Infant Sleepwear?

Infant sleepwear is designed to keep your baby snug, secure, and comfortable during their early months. The two most common types of infant sleepwear are sleep sacks and swaddles.

Sleep Sacks and Swaddles:

  • Swaddles: Typically used for newborns, swaddles provide a tight wrap that mimics the comfort of the womb, helping to soothe your baby and reduce the startle reflex.
  • Sleep Sacks: As your baby grows, sleep sacks offer a bit more room for movement while still keeping them warm and safe. They are like wearable blankets, designed to eliminate the risks associated with loose blankets in the crib.

Benefits of Sleep Sacks:

  • Safety: Sleep sacks reduce the risk of Sudden Infant Death Syndrome (SIDS) by keeping loose blankets out of the crib.
  • Comfort: They provide warmth without the risk of overheating, ensuring your baby stays at a comfortable temperature.
  • Startle Reflex Prevention: By keeping your baby snug, sleep sacks help manage the startle reflex, which can often wake them up.

When to Stop Using Sleep Sacks:

Most babies outgrow the need for sleep sacks between 6 to 12 months. During this time, they become more mobile, starting to roll over, crawl, or even stand up in their crib. These developments indicate that a sleep sack might become too restrictive, and it might be time to transition to toddler sleepwear.

Top 4 Signs Your Baby is Ready to Transition

As your baby grows, their sleepwear needs will change. Recognizing when it’s time to transition from infant sleepwear to toddler sleepwear is key to ensuring your child’s comfort and safety.

1. Increased Mobility

One of the most obvious signs that your baby is ready to transition is increased mobility. When your baby starts rolling over, crawling, or pulling up to a standing position, it’s a clear indicator that they need more freedom of movement than a sleep sack or swaddle can provide.

2. Discomfort in Sleep Sacks

If your baby begins to show signs of discomfort or frustration in their sleep sack, it’s another strong signal that a change is needed. They might fuss or try to wriggle out of the sleep sack, indicating that they feel restricted.

3. Outgrowing the Sleep Sack

Sleep sacks come in different sizes, but eventually, your baby will outgrow even the largest sizes. When your baby looks cramped or the sleep sack becomes tight around their shoulders and legs, it’s time to transition to more suitable sleepwear like premium adult blankies.

4. Developmental Milestones

Pay attention to other developmental milestones, such as starting to sit up or even taking their first steps. These milestones often coincide with the need for more flexible sleepwear that allows for greater movement and comfort.

Choosing the Right Toddler Sleepwear

As your baby transitions into toddlerhood, selecting the right sleepwear becomes essential for their comfort and safety. Here’s what to consider when choosing sleepwear for your growing child.

Comfort and Safety First

When picking out toddler sleepwear, the most important factors are comfort and safety. Opt for pajamas that are snug but not too tight. This snug fit helps to reduce the risk of fire hazards, as loose clothing can easily catch fire.

Material Matters

The fabric of the sleepwear is the key. Look for breathable, natural fabrics like cotton. Cotton is soft, and gentle on your toddler’s skin, and helps regulate body temperature, keeping them comfortable throughout the night.

Seasonal Considerations

Adjusting sleepwear according to the season is important to maintain your toddler’s comfort. In warmer months, choose lightweight, short-sleeved pajamas or even cotton sleep shorts. For colder weather, opt for long-sleeved pajamas and consider layering with a sleep sack or wearable blanket suitable for toddlers.

Flame-Resistant or Snug-Fitting

Ensure that the pajamas are either flame-resistant or snug-fitting. Flame-resistant pajamas are treated with chemicals to reduce the risk of catching fire. If you prefer untreated fabrics, snug-fitting pajamas are an alternative because they are less likely to catch fire.

Easy to Wear and Remove

Toddlers are often active and may resist getting dressed for bed. Choose pajamas that are easy to put on and take off, especially if your toddler is potty training. Pajamas with zippers, snaps, or elastic waistbands can make the bedtime routine less of a struggle. 

For added fun, consider mom & kid matching sets. These not only look adorable but can also make your toddler more excited about getting ready for bed.

Transitioning from Crib to Bed: What Should You Do?

Transitioning from a crib to a toddler bed is a significant milestone in your child’s life. It often coincides with the need to update their sleepwear to accommodate their growing size and increased mobility.

Making the Move:

When your toddler starts climbing out of the crib or outgrows it, it’s time to consider moving them to a toddler bed. This transition can be both exciting and challenging, but with the right approach, it can be smooth and stress-free.

Safety Tips:

  • Choose a Safe Bed: Ensure the toddler bed is low to the ground to prevent injuries from falls. Look for a bed with safety rails on the sides to keep your child from rolling out.
  • Secure the Room: Make sure the room is toddler-proofed. Secure heavy furniture to the walls, cover electrical outlets and remove any small objects that could be a choking hazard.
  • Comfortable Sleep Environment: Keep their favorite blanket or sleep item in the new bed to provide a sense of security and familiarity. Consistency is key to making them feel comfortable in their new sleeping space.

Comfortable Sleep Environment:

Creating a cozy and inviting sleep environment can help your toddler adjust to their new bed. Use their favorite bedding and consider adding some fun, child-friendly decorations to make the transition more exciting.

Bedtime Routine:

Maintaining a consistent bedtime routine is crucial during this transition. Keep the same rituals, such as reading a bedtime story, singing a lullaby, or having a warm bath before bed. Familiar routines help signal to your toddler that it’s time to sleep, even in their new bed.


Transitioning your child’s sleepwear from infant to toddler is a key step in their growth. Recognizing the signs that your baby is ready for a change helps ensure they stay comfortable and safe during sleep.

Choosing the right sleepwear is crucial. Look for comfortable, breathable fabrics and ensure a snug fit. This keeps your toddler cozy and reduces safety risks.

These changes ensure your toddler stays cozy and secure, making the transition smooth and positive. Sweet dreams to your growing little one!
