Parent tip
Set out bubbles before inviting your toddler in so the first minute feels smooth.

Blow bubbles face-to-face and wait for your toddler to say 'more' or 'pop' before blowing again.
Tiny Steps
Set out bubbles before inviting your toddler in so the first minute feels smooth.

Back-and-forth between you — words, gestures, shared pretend. Connection is the real outcome here.
Sit facing your toddler and blow a few bubbles. Let them pop them with delight. Then STOP. Hold the bubble wand ready but don't blow. Look at them expectantly. Wait for a sound, a sign, a word — 'more', 'pop', 'bubble', or even just an excited noise. THEN blow more. This creates a communication loop: I want something → I use my voice → I get it.
Bubbles are highly motivating — toddlers WANT more. Using that motivation to encourage communication (even a grunt means 'more') teaches that their voice has power. The face-to-face position is specifically recommended by Speech and Language UK for building communication skills. 'Pop' and 'more' are common early words because they're useful and fun.
