The impact of developmental milestones on children's sleep

Every child is unique, and their sleep patterns are influenced by many factors - one of which is developmental milestones.  Sleep changes during these milestones are a normal part of your child’s wider sleep journey.  Other factors, such as naps, bedtime routines, sleep environment, and independent settling skills also influence sleep patterns.  This post focuses on milestones and strategies to help navigate them smoothly, as one piece of the bigger picture.

Understanding developmental milestones

Developmental milestones are key achievements children reach as they grow, including physical, cognitive, social, and emotional growth.  From rolling over and crawling to babbling and walking, each milestone represents a significant leap in development.

As children progress, their sleep patterns may temporarily change. For example:

• A baby learning to crawl may become more restless at night.

• A toddler practising new words may wake more frequently as they explore language during sleep.

How milestones can affect sleep quality

The impact of milestones on sleep varies from child to child:

• Some children experience shorter naps or night wakings.

• Others may benefit from increased daytime activity, particularly outdoors, which can support deeper, more restful sleep.

It’s normal for sleep to temporarily shift during developmental leaps.  Knowing this can help you both with how you respond and with how you experience these changes.

Coping strategies for parents

Navigating sleep changes during developmental milestones can be challenging, but these strategies can help:

• Establish a consistent routine:  a predictable bedtime routine provides stability and helps children adjust to sleep changes.

• Create a sleep-friendly environment: keep the bedroom dark, quiet, and free from distractions.

• Be patient and supportive: understand that disruptions are temporary. Comfort and reassurance go a long way.

• Provide practice during the day: allow your child time to practise rolling, crawling, walking, or talking.  This reduces the desire to use new skills at night.

• Be consistent: stick to sleep routines even if nights are disrupted; consistency helps your child navigate temporary ‘sleep hiccups’ more smoothly.

If your child’s sleep is frequently disrupted and you’re feeling unsure how to respond, you’re not alone.  Small changes can help, but sometimes a personalised approach provides the clarity and confidence parents need.  You’re welcome to book a free discovery call to explore strategies tailored to your child’s needs.

Personalised support can be particularly helpful if:

• Your child’s sleep is badly disrupted during developmental milestones.

• Night wakings, early mornings, or short naps are becoming stressful.

• Adjusting routines and environment hasn’t improved sleep.

• You want guidance tailored to your child’s age, temperament, and family routine.

• You would like a step-by-step plan you feel confident implementing.

A consultation helps you understand your child’s unique sleep patterns and provides practical strategies to support longer, more restorative sleep while reducing stress for you and your family.
