Chickenpox in Babies, Toddlers, and During Pregnancy

If your baby wakes up more often at night, has a reduced appetite, and now you notice small red spots appearing on their skin, could it be chickenpox? 

As a Certified Sleep Sense Consultant at Lullabub Sleepers, I’ve supported many parents through the ups and downs of baby sleep, especially when illness strikes—and chickenpox is one of the most challenging. It not only makes your baby uncomfortable but also disrupts their sleep, making the upkeep of the fruits of sleep training even harder. 

In this guide, I’ll walk you through everything you need to know about chickenpox in babies, toddlers, and during pregnancy—how to ease discomfort, manage sleep disruptions, and recognize when to seek medical advice. 

What is Chickenpox? 

Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus (VZV). It leads to an itchy, blister-like rash, fever, and general discomfort. 

While mild in most children, chickenpox can be serious in newborns, pregnant women, and those with weakened immune systems.

How Do Babies and Toddlers Get Chickenpox? 

Chickenpox spreads easily through: 

✅ Direct contact with blisters ✅ Airborne transmission from coughing or sneezing ✅ Touching contaminated surfaces 

If your baby or toddler has been around someone with chickenpox, there’s a high chance they’ll develop symptoms within 10-21 days. 

Symptoms of Chickenpox in Babies and Toddlers 

Chickenpox usually follows these stages: 

1. Early Symptoms (1-2 Days Before Rash Appears) 

🔹 Fever 

🔹 Loss of appetite 

🔹 Fussiness and irritability 

🔹 Sleep disruptions 

2. Rash Development (3-5 Days) 

🔹 Red spots appear on the face, chest, and back 

🔹 Spots turn into fluid-filled blisters 

🔹 Blisters burst and form scabs 

3. Healing Stage (1-2 Weeks) 

🔹 Scabs fall off naturally

🔹 Itching improves 

🔹 Sleep and appetite return to normal 

Chickenpox and Sleep Training a Baby 

Chickenpox makes the upkeep of the fruits of sleep training more challenging because itchiness, fever, and discomfort lead to frequent night wakings. If you’re currently facing sleep upheaval because of chicken pox, don’t panic—this is just a temporary setback. 

How to Manage Sleep During Chickenpox 

✅ Stick to the Routine – Even if your baby wakes up more, maintain a consistent bedtime schedule. ✅ Cool, Comfortable Sleepwear – Dress your baby in light, breathable cotton pajamas. ✅ Lukewarm Baths – Oatmeal or baking soda baths soothe the skin and help relax your baby before bed. ✅ Use a Humidifier – Helps with congestion if your baby also has a cough. ✅ Extra Comfort When Needed – If your baby is unusually fussy, offer gentle cuddles and rocking to help them settle. 

Whatever happens when Chickenpox is at its worst, let it happen. But once your baby recovers, gently guide them back to independent sleep by implementing age-appropriate sleep strategies. 

Is Chickenpox Dangerous for Babies? 

For newborns under 6 months, chickenpox can be more severe, leading to complications like pneumonia or dehydration. Seek medical attention immediately if your baby: 

🚨 Has difficulty breathing 🚨 Develops a high fever (above 39°C) 🚨 Shows signs of dehydration (fewer wet diapers, dry lips) 🚨 Becomes extremely lethargic 

Chickenpox During Pregnancy – What You Need to Know 

If a pregnant woman catches chickenpox, there are risks to both her and the baby: 

🔹 First 20 Weeks: Higher risk of congenital varicella syndrome (which may cause birth defects). 

🔹 Near Delivery: The baby may be born with neonatal varicella, which can be severe. 

What to Do? 

✅ Get medical advice immediately if you suspect chickenpox during pregnancy. ✅ Varicella-zoster immune globulin (VZIG) may be given to reduce complications. 

How to Prevent Chickenpox in Babies and Toddlers 

1️⃣ Vaccination – The chickenpox vaccine is available in Singapore and is recommended for children over 12 months. 

2️⃣ Avoid Exposure – Keep your baby away from infected individuals. 

3️⃣ Boost Immunity – Breastfeeding and a healthy diet can strengthen your baby’s immune system.

FAQs 

What if my 2-year-old has chickenpox and I'm pregnant? 

If you’ve had chickenpox before or received the varicella vaccine, you likely have immunity and there’s minimal risk. However, if you’re not immune, contact your doctor immediately, as chickenpox during pregnancy can pose risks to the baby, especially in the first 20 weeks or near delivery. 

Is it OK to be around someone with chickenpox when pregnant?

If you’re immune (from past infection or vaccination), there’s little to worry about. If you’re not immune, avoid direct contact and speak to your doctor about preventive measures like varicella-zoster immune globulin (VZIG) to reduce the risk of complications. 

How does chickenpox affect the baby during pregnancy?

If contracted in early pregnancy, chickenpox can lead to congenital varicella syndrome, causing birth defects. If it occurs close to delivery, the newborn may develop neonatal varicella, which can be severe. Immediate medical attention is required in both cases. 

Is chickenpox common in Singapore?

Yes, chickenpox is common in Singapore, but vaccination has significantly reduced its prevalence. The varicella vaccine is part of the recommended immunization schedule for children. 

How do you treat chickenpox when pregnant?

Pregnant women with chickenpox should seek medical attention immediately. Antiviral medication like acyclovir may be prescribed, and varicella-zoster immune globulin (VZIG) can help reduce complications if given early. 

What happens if a pregnant woman is exposed to chickenpox (NHS)?

According to the NHS, pregnant women exposed to chickenpox should contact their doctor immediately. A blood test may be done to check immunity, and if at risk, VZIG may be given to reduce the severity of the infection.

What happens if a baby gets chickenpox?

Most babies recover well, but newborns under 6 months or those with weakened immune systems may face severe complications. Symptoms include fever, rash, and irritability. Parents should monitor for breathing difficulties, dehydration, or high fever and seek medical care if needed.

Can my child have the chickenpox vaccine if I'm pregnant?

The chickenpox vaccine is a live vaccine and is not recommended during pregnancy. However, it is safe for your child to receive it while you’re pregnant, as transmission of the vaccine virus is extremely rare.

What happens if a pregnant woman is exposed to shingles?

If a pregnant woman has had chickenpox before, exposure to shingles is usually not a concern. However, if she has never had chickenpox and is exposed, she should contact a doctor to assess the need for VZIG. 

What precautions should be taken during chickenpox?

To prevent spreading, isolate the infected person, wash hands frequently, and avoid sharing personal items. Pregnant women and individuals with weak immune systems should avoid close contact with an infected person. 

Can I go to work if my child has chickenpox?

If you haven’t had chickenpox before, you may be at risk and should consult your doctor. If you’re immune, you can go to work but check your workplace policies regarding contact with infectious diseases. 

Why is toxoplasmosis bad during pregnancy?

Toxoplasmosis can cause serious birth defects, including eye damage, brain abnormalities, and developmental delays. It is commonly contracted through contaminated food, soil, or cat feces, which is why pregnant women are advised to avoid handling cat litter and raw meat.
