Introducing your pet to a new baby (or new partner)
The introduction moment itself matters less than the preparation beforehand — pets that adjust well to a new baby or partner are usually ones who had time to adjust to the surrounding changes first.
Prepare for the changes before the day arrives
If a baby or partner's arrival will change your pet's routine (less one-on-one time, a new room becoming off-limits, new sounds and schedules), start introducing those specific changes weeks or months ahead, gradually — not all at once on moving-in or homecoming day. A pet who's already adjusted to the routine change has far less to process when the person themselves arrives.
The introduction itself
Keep the actual first meeting calm and low-key rather than a big event — let your pet approach at their own pace, and reward calm behavior generously. For a new baby specifically, a piece of clothing with the baby's scent brought home before the baby is can help; for dogs and cats meeting a new partner, let the relationship build gradually through calm, low-pressure time together.
Our calm-down toolkit has go-to exercises if the transition brings up real anxiety, not just adjustment.
