Your baby follows the rattle with their eyes. You wait for a hand to come out—and it doesn't. It is easy to turn one quiet play session into a question about development.
Looking, batting, holding and deliberately reaching are different steps. If your baby watches a toy but does not yet grab it, look at their age and what they do across ordinary moments, offer a little safe floor play, and speak to your health visitor or GP if you are concerned. You do not need to make your baby “pass” a toy test first.
What is typical around four to six months?
The CDC's four-month milestones include swinging an arm at toys and holding a toy placed in the hand. Its six-month milestones include reaching to grab a toy the baby wants. That is a useful distinction: a swipe or a brief hold is not the same action as spotting a toy, reaching for it and taking it.
These ages describe skills that most children show by that age; they are not a deadline for every baby and are not a diagnostic test. A baby who is tired, hungry or interested in your face instead may simply ignore the rattle in that moment. But if a milestone is not emerging, you notice a change, or your instinct says something is off, raise it with a professional rather than relying on a blog or an app for reassurance.
If your baby was born prematurely, their clinician may use corrected age when discussing development. Our corrected-age guide explains the term, but your neonatal team or health visitor can put it in the context of your baby.
A two-minute play invitation, not a test
Try this when your baby is awake, content and supervised:
- Put them on a clear floor mat on their back. Sit close and show one intact, age-safe, easy-to-hold toy where they can see it. Keep cords, small parts and anything that could cover their face away.
- Let them look. Move the toy slowly to one side, then hold it near—not far beyond—their comfortable reach. Pause. A look, a hand opening, a swipe or a reach is all useful to notice.
- If they are interested, offer the toy at their hand. If they turn away or fuss, stop and cuddle them. You can try another time; there is no required number of repetitions.
The NHS suggests placing toys near babies from around four months. It also recommends awake, supervised tummy time with toys nearby, starting little and often. Tummy time is play while awake, never a sleep position. You do not need a specialist toy or a long session. Your voice and face may hold their attention better today; our five-minute play ideas offer other small options.
When to ask someone to look with you
Contact your health visitor or GP if your baby is not showing an expected skill, has lost a skill they used to have, seems to use one side much less than the other, or you have a concern you cannot shake. The NHS-linked West Yorkshire Healthier Together hand-skills guide says to ask for advice if a baby cannot reach for objects by six months or is not using both hands equally. The CDC also says to act early if a child loses a skill or you are concerned. You need not wait for the next routine review; NHS development reviews are not the only chance to ask.
A helpful note for that conversation is simple: “At play on the floor this week, she watched the toy and swiped once with her left hand; I have not seen her reach with her right.” Describe what you have actually seen, rather than labelling your baby delayed. A clinician can consider the full picture and advise whether any assessment is needed. If your baby is acutely unwell or you are worried about an urgent change, seek medical help promptly instead of trying more play activities.
In OBubba's Grow → Milestones screen, you can mark a little first when it happens. The screen says the ranges are guidance, not a test, and points you to a health visitor or GP if something feels off. Grow → Activities offers age-appropriate play ideas; it does not assess or diagnose your baby's movement. Use either to remember a real moment or try a gentle game, never to replace a conversation about a worry. For a way to keep a record without comparing babies, see Milestones without the comparison spiral.
This is general information, not an assessment of your child. Watching closely is caring; asking for help is caring too. If a small record would help you hold onto what you noticed, explore OBubba.
