Motivate your child to ask for more bubbles. Blow a few rounds of bubbles, then stop, leaving the wand in the container and see if you can your child to request for you to take the wand out. Then put the wand up to your mouth, but don’t blow. See if you can get your child to request you to blow. If your child is an early learner, you may accept him reaching for the container or wand as a way of communicating his wants, or maybe a simple first letter sound, such as ‘ba’ for ‘blow’ is developmentally appropriate for him. For a child with more language ability, you can elicit the sentence “Please blow more bubbles”.
Motivate your child to comment about bubble play. Demonstrate commenting during play, then stop and point at a bubble with an excited look on your face and see if your child will make a comment on their own. You can give an early learner a sentence to fill in, such as “That bubble is _____” or for a child with more language ability, help them to communicate longer, more descriptive sentences.
