A bedtime routine that runs itself
Set it up once. Every evening then follows the same gentle arc: a quiet reminder, a few stories, and a soothing sound that plays until morning.
- Reminder
Right on cue
A gentle daily notification at the time you choose, so the evening begins the same way every night.
- Stories
Fades out gently
Queue a few favorites and set 15, 30, or 60 minutes. When time is up, the last story fades out gently.
- Soothing noise
Until morning
Waves, rain, or white noise take over and play softly for 1, 3, or 12 hours, so you can slip out of the room.
Line by line, in every language
Each line of every story is heard back to back in every language you choose — up to 3 at once. Children pick up new words by hearing them right next to ones they already know.
interleaved bilingual storytelling
- 5-year-olds
Hearing a story with 31 line-by-line language switches taught new words just as effectively as hearing each language in a single block.

Storybooks that mix a dominant-language narrative with second-language target words support retention, with older preschoolers benefiting most.

Mixing two languages within one session outperforms studying each language in separate blocks.

Read the full study notes
Researchers call this approach interleaved bilingual storytelling, and have tested it directly with bilingual children. In a randomized study, 5-year-olds heard a story with 31 line-by-line language switches and learned new words just as well as children who heard each language in a single block (Brouillard et al., 2022) . Among 2- to 5-year-olds, storybooks that mix a dominant-language narrative with second-language target words also support retention, with older preschoolers benefiting most (Read et al., 2021) . In adult learners, mixing two languages within one session likewise outperforms studying them in separate blocks (Libersky et al., 2025) .
