These are signs of healthy [cognitive](/cognitive) development. Every baby has their own pace, so think of these as a gentle map, not a checklist to tick.\n\n## What you may notice\n- **Object permanence** — looking for a toy you partly hide, or watching where a ball rolls out of sight.\n- **Cause and effect** — pressing buttons, banging two blocks, or repeating an action to make something happen again.\n- **Simple imitation** — copying a wave, clap or peek-a-boo.\n- **Exploring on purpose** — turning objects over, putting things in and out of containers.\n- **Early understanding** — responding to their name and to simple words like \"no\" or \"bye-bye\".\n- **Pointing and looking** — following your point, or looking where you look.\n\n## The science, simply\nThe WHO ICF describes these as early *mental functions (b1)* — the building blocks of memory, attention and problem-solving.
