Do babies sleep more when sick? At first glance, the answer would be “yes” because babies sleep more when they’re unwell. However, the answer is not straightforward and can be very complicated in some situations.
Most babies sleep more when they are ill because the body is gearing up to fight the infection. This means that there may be an increase in temperature and a reduction in appetite and thirst. The body also begins to use up energy stores (including glucose) for healing, which causes fatigue and irritability.
A recent study found that there is no relationship between shortened daytime sleep duration and nighttime sleep duration (or naps) in healthy infants. We now know that babies don’t need to nap more when they’re ill.
When their biological clocks have matured, babies first begin to nap between 3 and 4 months of age. Naps are an opportunity for the body to rest and grow.
Growing babies need plenty of sleep — and healthy babies do not need more sleep when they’re sick because their bodies require the same amount of sleep no matter what.
Do babies sleep more when sick?
Most sick children usually sleep more, but they often fall asleep and wake up more frequently at night. This is because they may not be able to sleep deeply at night.
After all, they’re fussy and want to be fed or changed, or because they’re feeling restless (can’t settle). In this state of being, they may find it hard to get back to sleep after waking in the middle of the night.
However, the amount of night sleep does not necessarily go up or down when a baby is unwell, and it may just change from night to night.
Also, many factors affect how much babies sleep at night and during the day. These include maturity (baby’s age), temperature (too hot or too cold), feeding practices, and newborn colic. All these factors can influence whether your baby sleeps longer at night when sick.
Why do babies sleep more when sick?
It may have to do with a baby’s limitations and recovery. When babies are sick, they can’t move around as much, so they need to rest more to get better.
Extra sleep may also be needed because the baby is not as alert and active when ill. If it seems clear that your baby needs extra sleep, then encourage her to rest —remember that extra sleep does not mean better, happier, or healthier.

The researchers found some trends but very few significant differences between daytime and nighttime sleep. Infants do not need more rest when sick for their bodies to heal.
Healthy babies don’t need to sleep more when they’re sick, so be sure to take good care of your baby even if she is sleeping a lot.
How to handle sleep when your baby is sick?
If your baby is sick, remember that she doesn’t need to sleep more. If she seems to be sleeping more than usual, try changing her position so that she can rest more comfortably.
If your baby sleeps a lot during the day and won’t feed or drink much (poor appetite), try offering low-fat, easily digestible meals and fluids.
Be sure that there are no hazards in the room (such as toys or blankets), and make sure there is a heat source to keep your baby warm.
Here are some tips on how to manage sleep when your child is sick:
1. Our children are programmed to have more restful sleep when they’re sick. However, there are certain ways you can help your little one stay well and get better.
2. Raise the temperature in your baby’s bedroom. If your baby is sleeping more, perhaps her room needs to be cooler. Keep her bedding clean and free from any blankets that might be causing a suffocation hazard if she wraps up in them, which could cause pneumonia.
3. Make sure your baby is hydrated and comfortable throughout the day. Feed your baby every two to three hours in case her appetite drops.
4. Identify triggers of crying, whether it’s hunger or an upset tummy, so you know what to do before her needs become too extreme to manage.
5. Encourage a warmer, more humid environment.
6. Maintain a consistent routine.
7. Make sure there are no hazards in the room, such as toys or blankets that could be suffocating your baby.

3 Ways To Manage Daytime Sleep When Babies Are Sick
