Fill a lunchbox or small bag with a variety of containers: a clip-lock box, a screw-top bottle, a zip-lock bag, a banana, and a wrapped snack bar. Your toddler works through each one, opening and closing them independently. This is genuine nursery rehearsal — the containers and wrapping types they will encounter at every mealtime. The fine motor challenge varies with each container, and the reward of finding a real snack inside keeps motivation sky-high.

Best for this moment

for calmer, lower-pressure moments, especially when you need an indoor option.

Parent tip

Set out plastic bottles and plastic containers before inviting your toddler in so the first minute feels smooth.

What success looks like

A good outcome is a few minutes of engaged play, some back-and-forth with you, and a small sign of progress in cognitive skills.

  1. Gather 4-5 different containers with various opening mechanisms: clip-lock, screw-top, zip-lock, peelable
  2. Place a small healthy snack or toy inside each one
  3. Put all the containers into a lunchbox or small bag
  4. Sit together and ask: 'Can you open this one? Let's see what is inside!'
  5. Let your toddler try each container independently — resist the urge to help immediately
  6. If they struggle, show the motion once slowly, then let them try again
  7. Once all containers are open, practise closing each one back up
  8. Celebrate the effort: 'You opened every single one — you are ready for lunchtime!'

Why it helps

Opening containers requires bilateral coordination, grip strength, and motor planning — all fine motor skills that develop rapidly between 24 and 42 months. Practising at home in a calm environment means your toddler arrives at nursery already confident with the exact container types they will face, reducing frustration and the need for staff help at mealtimes. This aligns with the EYFS Physical Development goal of managing self-care tasks with increasing independence.

Variations

  • Use the actual lunchbox and containers you plan to send to nursery so the practice is directly transferable.
  • Add a timed element for older toddlers: 'Can you open them all before the sand timer runs out?'
  • Include a water bottle with a flip-top or push-pull spout — drinking independently at nursery is just as important.

Safety tips

  • Ensure all containers are clean and any food inside is age-appropriate and free from choking hazards.
  • Avoid containers with sharp edges or lids that could pinch small fingers.
  • Practise at a relaxed pace — rushing creates frustration and negative associations with the lunchbox routine.

When to pause and seek extra support

Stop if your child becomes distressed, unsafe, or consistently frustrated by the activity. If play, behaviour, or development worries keep showing up across settings, check in with a qualified professional.
