Pets and Newborns: What to Look Out For

Pets and Newborns: What to Look Out For

- By Monica Bykov, RN, IBCLC, NCS - 

As a registered nurse and certified newborn care specialist, I’ve helped hundreds of families navigate the tender transition of bringing a newborn home. One topic that often comes up—and one that deserves more attention—is how pets fit into the picture.

For many families, pets are their first “babies,” and understandably so. They’re beloved companions, loyal protectors, and in many cases, an important part of the family dynamic. But when a new baby enters the home, everything shifts. Even the calmest, most well-trained pets can react in unpredictable ways to crying, unfamiliar scents, and sudden changes to their environment.

Here are a few practical—and professional—things I always guide parents to watch for when pets and newborns are under the same roof.

1. Sensory Overload for Everyone (Especially Your Pet)

Babies bring new sounds (crying), smells (diapers, formula, creams), and routines. This sudden shift can overwhelm even the most mellow animals. Dogs, in particular, may interpret high-pitched cries as distress signals and become agitated or anxious. Cats, who thrive on routine, may start acting out—hiding, refusing food, or marking territory.

To ease the transition, I recommend gradually introducing baby-related items—such as swings, lotions, or even recorded baby cries—before baby arrives (1). This allows pets to associate those sounds and smells with calm experiences.

2. Health Concerns and Allergy Awareness

Infant immune systems are immature, making them more vulnerable to bacteria, parasites, and allergens. While most pets are safe around babies, there are a few medical precautions worth considering.

  • Toxoplasmosis (from cat feces) is a risk for pregnant women but can also be harmful for babies if a litter box isn’t well-maintained. Gloves and proper hand hygiene are a must.

  • Fleas and ticks can spread disease to infants. Always keep pets on an appropriate, vet-approved preventative regimen.

  • Pet dander may exacerbate eczema or trigger respiratory issues in sensitive infants. If there's a family history of allergies or asthma, I suggest using HEPA filters and keeping pets off bedding and upholstered baby gear (2).

3. Safety First—Always Supervise

This might seem obvious, but it needs to be said: never leave a newborn alone with a pet. Even the most loyal dog or gentle cat can behave unpredictably in the presence of crying, sudden movement, or unfamiliar smells.

I’ve seen pets accidentally jump into bassinets, knock over baby swings, or nibble on pacifiers. It’s not out of malice—it’s curiosity. But supervision is non-negotiable, especially in the first few months.

4. Create Boundaries Without Exclusion

Pets thrive on consistency, and it’s easy for them to feel displaced once the baby arrives. I encourage families to create a “safe space” for pets—a bed, a room, or a quiet corner—where they can retreat when things get hectic.

At the same time, include them in calm bonding moments. Allow them to sit nearby during feedings or stroller walks. Gentle exposure helps reduce jealousy and promotes a positive association with the baby.

5. Building a Beautiful Bond Takes Time

Some of the most heartwarming moments I’ve witnessed have been between toddlers and their family pets. But those bonds are built over time, with intentional boundaries and positive reinforcement.

Introducing baby blankets with the newborn’s scent before coming home, giving your pet attention daily (even in small doses), and praising calm behavior all help foster trust.

Final Thoughts

As a nurse and newborn care provider, my role is to help families feel confident—not overwhelmed. Pets and babies can absolutely coexist safely and lovingly, but it takes preparation, awareness, and respect for everyone’s adjustment process.

With the right precautions and consistency, that early curiosity turns into lifelong friendship—and there’s nothing quite like watching your baby grow up with a furry best friend by their side.
