Fill a jam jar with water, add a glow stick (cracked to activate), and watch the jar glow softly in the dark. Stick star stickers on the outside for decoration. The child has MADE their own light — it is not just a night light, it is something they created to protect themselves. This sense of agency over the dark is far more powerful than any plug-in lamp, because the child feels they have the tools to manage their fear.

Best for this moment

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

Parent tip

Set out plastic containers and stickers 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 creativity.

Instructions

Get ready
  • Gather materials: a clean jam jar (plastic if possible), a glow stick, star stickers, water.
  • Let your child decorate the outside of the jar with star stickers: 'We are making a star jar to light up the dark!'
  1. Gather materials: a clean jam jar (plastic if possible), a glow stick, star stickers, water.
  2. Let your child decorate the outside of the jar with star stickers: 'We are making a star jar to light up the dark!'
  3. Fill the jar with water together — use a small jug so they can pour.
  4. Crack the glow stick (adult does this) and drop it into the water: 'Watch! It is glowing!'
  5. Put the lid on tightly and turn off the lights: 'Look at your star jar! It is shining just for you!'
  6. Place it beside the bed: 'Your star jar will glow while you sleep. The dark is not scary — it is where stars live.'
  7. Make looking at the star jar part of the bedtime routine: check it is glowing before lights out.
  8. When the glow stick fades (next day), talk about making a new one: 'Shall we make another star jar tonight?'

Why it helps

Fear of the dark is a developmentally normal phase that typically peaks between 2-4 years as children's imaginative abilities outpace their ability to distinguish fantasy from reality. Research shows that giving children a sense of control over their fear (creating their own light source) is more effective than simply installing a night light, because self-efficacy — 'I can do something about this' — is the antidote to helplessness. The craft element also creates a positive pre-bedtime ritual that replaces anxious anticipation with creative engagement.

Variations

  • Use fairy lights in a jar instead of a glow stick for a longer-lasting version (battery-operated, not mains).
  • Add glitter to the water before sealing — the glitter catches the glow and creates a swirling galaxy effect.
  • Make a 'bravery jar' — each night the child sleeps with the light off, add a star sticker to the jar. When the jar is full of stickers, celebrate.

Safety tips

  • Use a plastic jar, not glass — jars beside beds can be knocked off in the night.
  • Seal the glow stick inside the jar securely — glow stick liquid is mildly toxic if ingested. The jar must not be opened.
  • Keep fairy lights battery-operated, never mains-powered, and check batteries are secured behind a screw-down panel.

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.
