Lizzy Sleep

Parents who are up at 3 a.m. with a baby who will not settle are the people Lizzy Sleep is built for.

Lizzy Sleep is a baby sleep coaching app that gives you personalized sleep plans and a chat you can use at any hour, day or night.

Think of it as a pediatric sleep consultant you carry in your pocket.

The goal is independent sleep for your baby, and the app approaches it through guided programs.

The chat covers a range of problems, from sleep training to soothing a newborn, so you can ask a question in the moment instead of waiting for an appointment.

Lizzy Sleep was founded by sleep consultant Ensley Nesbitt and Ernie Park, and its pitch rests on three things: consistency, accountability and personalization.

That fits the real difficulty of sleep training, which is sticking with a plan when you are tired.

A chatbot cannot replace a clinician for medical worries, but for day-to-day sleep questions the always-on chat is the main draw.
