Why Do Babies Flailing Arms and Legs Before Sleep? Understanding the Possible Causes
Parents often find it annoying when their babies bang their arms and legs before sleep.

Developmental Milestones And Muscle Strength: A Reason for Your Baby to Flail Their Arms and Legs?
Let’s first talk about milestones. Developmental milestones are essential for a baby’s overall growth. As your baby grows, an important milestone is muscle strength.
Babies will usually fail their arms and legs before they go to sleep. One reason? This helps them strengthen the muscles in their limbs.
This movement also helps with coordination and balance. Plus, it helps build strong core muscles. As babies progress from rolling over to crawling to walking, their muscle strength increases accordingly.
Parents must encourage physical activity such as stretching and tummy time. These activities help the baby can reach these milestones properly.
Once a baby has reached the milestone of walking, they can begin more strenuous activities. In time, your baby will be doing things like running or climbing stairs.

If you think your baby’s flailing is due to weariness or overstimulation, visit a doctor for advice on how to help.
Reflexes and Nerve Connections: The Moro Reflex & Why Your Baby is Flailing
Startle reflexes, called the Moro reflex, are another reason babies flail before bed. This startle reflex keeps your baby safe. External stimuli, like a loud noise, trigger it.
Babies have powerful newborn reflexes that cause them to flap their arms and legs when stimulated. Young children may flail their arms and legs as their brain-body nerve connections grow.
