At 2am, time moves strangely. Your newborn’s cries feel louder, your brain feels foggier, and every tip you’ve ever heard about sleep and soothing blurs into static. Do you try a swaddle? More sound? An extra feed?

Problem is, your pediatrician’s office has been closed for hours, and you know even your ride-or-die parent pals are blissfully snoozing with phones on “do not disturb.”

Now, in those moments when you need immediate and reliable guidance long after the sun went down (or in the middle of naptime or anytime in between!), you can simply…ask Happiest Baby!

The Happiest Baby App now gives families 24/7 to our smart parenting helper. With it, you’ll get instant, around-the-clock sleep support for newborns to tiny toddlers.

Our chatbot draws on the work of pediatrician Dr. Harvey Karp, creator of SNOO and best‑selling author of The Happiest Baby on the Block. His practical tips have reshaped how parents soothe cries, improve sleep, and build healthy routines that grow with their child.
