Love

Warmth that doesn't depend on behavior.

These lines simply say that your child is loved and that you're glad they exist. They don't ask for anything and they don't compare your child to anyone.

The 8 phrases

• I love youSpeak from your heart. Your voice is the greatest sleep sound.
• You are lovedSay it the way you would at bedtime.
• You are my babyA simple sentence is enough.
• Sleep in my loveLet the last word land softly.
• My heart is with youUnhurried. One breath between words.
• I adore youKeep it short enough to loop.
• I love you just as you areWarmth with no conditions attached.
• I'm so glad you're mineSmile while you say it if you can.

The line under each phrase is the tip shown in the app when you record it.

What the research says

• A parent's sensitivity, meaning noticing a child's signals and responding warmly, is linked to secure attachment. A review of 174 studies covering about 23,000 children found a moderate link (r = .25).
• An earlier review of 66 studies reached a similar conclusion, adding that sensitivity matters a lot but isn't the only ingredient.
• In a study that followed children over time, parents' warmth predicted higher self-esteem, while “overestimating” a child (seeing them as more special than others) predicted narcissism.

How we used it

Every line in this folder expresses love or gladness. None uses superlatives (“the best,” “so special”), because the research above separates warmth from overvaluing.

What we don't know

• These are associations across many families' everyday parenting. They don't show that a recorded phrase at bedtime changes anything.
• No study has tested these exact phrases or a recording-at-bedtime approach.
