Three months in, and the fog is starting to lift. Somewhere between the late-night feeds and the endless burp cloths, your baby has turned into a little person with opinions – and a smile that seems made just for you. Many babies around this age are lifting their heads a bit higher during tummy time, discovering their own hands and “talking” back in coos and squeals (every baby has their own timeline, so there’s no need to compare).
Whether you’re posting a monthly milestone photo, writing in a baby journal or sending a note to the grandparents, here are fresh, copy-ready lines for your 3-month-old. Tap Copy on any card and paste it straight into Instagram, WhatsApp or Facebook.
