    • Signs of Stress in Your Baby

    Infants can get stressed just like grown-ups. If your child resists sleep, take a minute to make sure her problem isn’t a sign of stress. She may be troubled by:

    • Yelling or fighting—in real life or on TV.
    • Scary situations, including barking dogs, loud noises, an unfamiliar bedroom or a new or unfriendly people (a new sitter or teacher, or even a grandma who hasn’t visited in a while).
    • Separations, such as having to stay with sitters or having a regular caregiver suddenly leave.

    Many other factors can contribute to stress in babies. With all the new stimuli in the world, if you as parents are feeling stressed, imagine what the baby could be feeling!

    The above list  can especially upset fragile, super cautious infants who tend to get scared, lonely and extra cranky when unexpected changes occur.

    Signs of Stress in Your Baby

    The science of stress is deeply correlated to cortisol levels, both in adults and babies. Cortisol is known as the “fight or flight” hormone. Stress can take many forms but there are some serious signs we should be aware of in babies that can definitely negatively impact their sleep.

    • hiccupping
    • yawning
    • sneezing
    • frowning
    • looking away
    • squirming
    • frantic, disorganized activity
    • arms and legs pushing away
    • arms and legs limp and floppy
    • skin color changes

    Studies have shown that dealing with your baby in gentle ways—cuddling, caressing, sweet talk, etc—can all help lower cortisol levels and thus lower stress in babies.

    If you think stress is part of the problem, do what you can to protect your honey from these upsets and start a great bedtime routine to get her back in balance.
