Baby outer clothing?

For baby outer clothing, the basic principle is layering and matching the season. In cold weather, a good rule is to dress your baby in one more layer than what makes you comfortable—babies can't regulate their temperature as well yet, so a slightly extra layer is the safe side. A cotton base layer, a wool or fleece middle layer, and a windproof outer shell are the most common combination. Don't forget hats, gloves, and socks because babies lose a lot of heat through their heads and wrists.

In warm weather, thin, light-colored, cotton, breathable fabrics work best—a single layer is enough. Always prioritize direct sun protection with hats and shade; for babies under 6 months, physical protection (shade, hats, thin covering) is preferred over sunscreen.

For spring and fall, breathable, easily removable layers—rompers or full-zip tops—are practical. Avoiding overheating matters more than keeping them warm: you can check by touching the back of your baby's neck to see if they're sweaty or cool; cold hands and feet alone don't mean they're cold.
