What to Do If You Kissed Your Baby with a Cold Sore (Anxious Mom Guide)

Hello, lovely mama—welcome! I hope you are doing well.

If you’re here due to a cold sore or that tingle on your lip after kissing your baby, listen up: You are not a bad mother. You love your child more than life itself, and this was simply an accident.

There comes a time for all us when we are running on two hours of sleep and do something without thinking. It's normal to feel scared. But instead of panicking, let's focus on being proactive and helpful. I am here to tell you exactly what to do next, what to watch out for, and how to keep your little one safe.

Step 1: Wash the Area Gently Right Away

If you just kissed your baby and the spit is still fresh on their skin, go ahead and do this first:

• Be very gentle: Take a soft washcloth with a little bit of mild baby soap and warm water.
• Do not scrub: Gently wipe the spot where your lips touched their skin. Scrubbing can cause tiny scratches and make it easier for bugs to get in.
• Wash your own hands: Wash your hands with warm water and soap for a full 20 seconds before and after doing this.

Step 2: Call Your Pediatrician Promptly

Do not wait around to see if something happens, and please do not try to guess if your baby will be okay on your own.

• Call the doctor’s office: Give your baby’s doctor a quick call.
• Tell them the details: Tell them exactly how old your baby is, where you kissed them, and if your cold sore was open, weeping, or just a tiny bump.
• Ask for a plan: The doctor will tell you exactly what to do based on your baby's age. If your baby is a newborn (under 3 months old), doctors take this very seriously because tiny babies have brand-new immune systems that are still growing.

Things to Watch For: The Warning Signs

The virus that causes cold sores is called Herpes Simplex Virus (or HSV). In adults, it just causes an annoying lip sore. But in tiny babies, it can make them very sick.

You will need to watch your baby closely for the next 7 to 14 days. Make sure to check their whole body during diaper changes and baths.

Call emergency services or go to the nearest emergency room immediately if you see any of these signs:

• Little blisters: Look for tiny, fluid-filled bumps or red spots around their mouth, eyes, or anywhere on their skin.
• A fever or low temp: A temperature of 100.4°F (38°C) or higher is a major warning sign for a baby. Also, watch out if their body feels unusually cold.
• Extreme sleepiness: If your baby is very hard to wake up, won't open their eyes, or seems completely floppy and exhausted.
• Poor feeding: If they suddenly refuse to nurse, won't take their bottle, or seem too tired to suck.
• Irritability: If they are crying constantly and nothing you do will soothe them.
• Eye problems: Look for red eyes, swollen eyelids, or any watery or thick fluid draining from their eyes.

Note: Please double-check your baby's physical health materials or thermometer box to verify standard temperature guidelines for your specific device.

How to Protect Your Baby While You Heal

Cold sores are sneaky. They are contagious from the very first moment you feel a tingle, all the way until the scab falls off and clean new skin grows back. Until your sore is completely gone, use these mother-to-mother safety rules:

• No kisses at all: This is the hardest part, mama. No kissing the baby on the mouth, the cheeks, the hands, or the feet. Shower them with air kisses instead!
• Wear a face mask: If you are holding your baby close, rocking them, or breastfeeding, put on a clean face mask. This stops your lips from accidentally brushing their skin and stops you from touching your own sore by mistake.
• Wash hands like crazy: Wash your hands before you pick up your baby, before making a bottle, and after touching your face. Keep hand sanitizer close to your rocking chair.
• Don't share things: Do not blow on their food to cool it down. Do not clean their pacifier by putting it in your own mouth. Keep your towels and cups completely separate from the baby's things.
• Be careful with breastfeeding: You can absolutely keep breastfeeding your sweet baby as long as you do not have any sores on your breasts. Just wear your mask while holding them close.
