How to Use an Object Permanence Box with Your Child at Home
An Object Permanence Box teaches babies that hidden things still exist. Play at home by sitting together, dropping a ball in so it disappears and reappears, using hand-over-hand help, waiting for your child to search, and naming each step — short, warm, 3–5 minute sessions, ideal around 8–14 months.
In this answer 5 sections
A toy that disappears and comes back is one of a baby's first lessons that the world is reliable — and an Object Permanence Box turns that lesson into joyful, hands-on play.
In short
An Object Permanence Box is a simple wooden box with a hole on top and a tray that catches a ball dropped inside — the ball vanishes, then reappears. You work on it at home by sitting with your child, dropping a ball in together, and celebrating when it rolls out, helping them learn that things still exist even when they can't be seen. Most babies enjoy this between roughly 8 and 14 months, and it builds attention, hand control and early problem-solving.
How to play at home
Set it up for success
- Sit on the floor facing your child, box between you, in a calm room with few distractions.
- Start with one ball. Drop it in slowly so they watch it disappear, then point to the tray as it rolls out — "Look, it came back!"
- Let them watch you a few times before handing them the ball.
Build the skill gently
- Hand-over-hand: gently guide their hand to drop the ball in, then let go so they retrieve it themselves.
- Pause and wait — give them time to look for the ball. That searching is the real learning.
- Name everything: "in… gone… here it is!" Simple, repeated words pair language with the action.
Make it your own
- No box at home? Use a tissue box and a small ball, or hide a toy under a cloth and reveal it together.
- Cheer every attempt, not just success. Warmth keeps them coming back.
- Keep sessions short — 3 to 5 minutes — and stop while they're still enjoying it.
When it helps to ask
If, by around 12–14 months, your child shows no interest in searching for a hidden toy, doesn't follow the moving ball with their eyes, or isn't reaching and grasping, it's worth a friendly developmental check — not a cause for alarm, simply a chance to support their next steps. Pairing this play with occupational therapy ideas can strengthen hand skills and attention.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
By around 12–14 months, look for interest in searching for a hidden toy, eyes following the moving ball, and reaching to grasp. If these aren't emerging, a friendly developmental check helps — it's support, not alarm.
In everyday life
Narrate the magic: say 'in… gone… here it is!' every single time. Repeated simple words paired with the action build both language and the idea that things still exist when out of sight.

Bring your questions to a first visitQuestions families ask
What age is an Object Permanence Box best for?
Most babies enjoy it between roughly 8 and 14 months, when they begin to understand that hidden things still exist. Every child develops at their own pace, so follow your child's interest rather than a fixed date.
I don't have a wooden box — can I still do this activity?
Yes. Use a tissue box and a small soft ball, or simply hide a toy under a cloth and reveal it together. The learning comes from the disappear-and-reappear surprise, not the equipment.
My child loses interest quickly — is something wrong?
Short attention is completely normal for babies. Keep sessions to 3–5 minutes, stop while they're still enjoying it, and try again later. If you have ongoing concerns, a developmental check can reassure you.
