Why the Preparation Window Matters
The weeks before your baby comes home are genuinely the most useful window you have. Your pet is still living in a predictable, low-stress environment — which makes it far easier to introduce changes gradually rather than all at once. Animal behavior specialists consistently note that abrupt shifts in routine and space are among the most common triggers for anxiety in resident dogs and cats when a newborn arrives.
This checklist is designed for households where a dog or cat is already living in the home before the baby's birth. If you're also thinking about the longer-term safety picture, our pet-proofing guide for homes with young children covers the broader hazards to address as your child grows and becomes more mobile.
Work through the checklist groups below in roughly the order presented — starting with vet and training foundations, then moving through environment, scent, and finally the day-of introduction itself.

What You'll Need to Work Through This Checklist
Most of these preparations cost little or nothing. A few items — like a veterinary behaviorist consultation or baby gate hardware — involve some expense, but many families find that investing time in these steps helps avoid more stressful (and sometimes costly) problems after the baby arrives. For context on managing pet-related household costs more broadly, see our affordable pet care hub.
Baby gates or room dividers
Create pet-free zones, particularly around the nursery, before the baby comes home.
Dog leash and collar or harness
Maintain control during the first supervised face-to-face introduction between your dog and baby.
Pet-safe calming aids (vet-approved only)
Support anxious pets during the transition period — always discuss options with your veterinarian first.
Recorded infant sound samples
Desensitize your pet to crying and cooing sounds in the weeks before the baby's arrival.
Crate or designated pet retreat space
Provide your pet with a secure, undisturbed space during the adjustment period.
Never Leave Pets and Infants Unsupervised
No matter how well-prepared or gentle your pet is, newborns and infants should never be left alone with a dog or cat — even briefly. This is a consistent recommendation from pediatric and veterinary safety organizations. Supervision means an adult is physically present and attentive, not simply nearby. Even calm, familiar pets can react unpredictably to a baby's sudden movements or sounds.
Watch for Stress Signals Before Problems Escalate
Pets communicate discomfort through body language long before any incident occurs. In dogs, watch for lip licking, yawning in tense moments, whale eye (visible whites of the eyes), stiff posture, or retreat. In cats, flattened ears, tail lashing, or hiding can signal distress. If you notice persistent or escalating stress signals, contact your veterinarian or a certified animal behaviorist promptly rather than waiting.
The Day of Arrival and the First Week
The day your baby comes home isn't the time to improvise. Having a clear, calm plan matters more than any single preparation step. Before you leave the hospital, ask a partner, family member, or trusted friend to give your pet a good walk or play session so they arrive home in a calmer state.
Bring home a blanket or item of clothing with your baby's scent before the baby comes home — this is one of the most research-supported strategies for easing a pet's initial response. Keep the first face-to-face meeting brief, positive, and fully supervised. Reward calm behavior; don't punish curiosity. If your pet shows persistent signs of anxiety or any concerning behavior during the first weeks, contact your veterinarian promptly — this is general guidance, and individual animals vary significantly.
