Every new parent has a mental list of questions that start with "can I...?" This guide tries to answer them comprehensively, in plain language, in one place. It covers the first eight to twelve weeks specifically — the newborn period when many of these questions are most pressing and when the guidance is most specific.
Three verdicts are used: ✓ Yes (safe and fine to do), ✗ No (avoid — safety or developmental reasons), and ! With care (fine with specific conditions or caveats). Where guidance differs between sources, we note it. Where evidence is evolving, we say so.
This guide covers general healthy, term newborns. If your baby was premature, had a difficult birth, or has any health concerns, always follow the specific guidance from your neonatal team or paediatrician — some of this guidance may not apply.
Never shake your baby
This is the single most important rule in newborn safety. Shaking a baby — even briefly, even in play, even in frustration — can cause severe and permanent brain injury or death. If you feel overwhelmed, put your baby down in a safe place (a cot or flat surface) and take five minutes to calm down. Call someone for support. This is always the right choice.
