When can a newborn start using sensory toys?
Right from birth, though "using" looks different than it will later. A newborn won't grab or shake a toy on purpose for a while yet. In the early weeks, it's more about what they can notice with their eyes and ears — a high-contrast card or a soft rattle sound counts as engagement, even if their hands stay closed the whole time.
Do newborns actually see in black and white?
Not entirely, but colour vision is limited at birth and takes a few months to catch up. This is why black-and-white and other high-contrast patterns tend to hold a newborn's attention better than pastel or multicolored toys—the bold contrast is simply easier for their eyes to pick out early on.
How long should I show a sensory toy to my newborn?
There's no set number that applies to every baby. A few minutes during an alert, calm period is usually enough. Watch your baby rather than the clock—if they turn away, fuss, or stop looking, that's a sign they've had enough for now, not a sign you're doing it wrong.
What should I avoid with newborn sensory toys?
Skip anything with loose ribbons, small detachable parts, or long cords near the crib, and keep hanging toys like mobiles out of grabbing range once your baby starts reaching. Beyond that, it's mostly about not over-relying on any one toy to "do the work"—newborns respond just as strongly, often more so, to a caregiver's face and voice.
