No more fight on sleep training!

My husband and I couldn’t agree on sleep training methods and it was causing lots of arguments. Cocoo took that pressure off because it tells what’s working vs not based on data and gives us a sleep training plan that we both agree on! The sleep schedule part is the highlight!

Best sleep schedule

I spent days trying to find a online schedule that works for my son and not just a template. Coco built one around his naps and habits and it adjusts with him! We’re not doing any formal sleep training just following the app’s suggestions - and he’s already napping longer and going down easier at night! Can’t believe I didn’t know this earlier.

Download it if you are new moms and dads!

As new parents, we were constantly worried about our baby’s sleep, naps, feeding, and daily routine. This app has been such a lifesaver! It’s super easy to track everything, and I really love the AI feature that analyzes our baby’s routine and gives helpful suggestions. It helps us better understand what our baby needs and establish healthier habits. We’ve already become more confident and less stressed as parents. I highly recommend this app to any new mom or dad!

An app that saved my sanity!!

Trying to go from 3 naps to 2 was a disaster. Short naps everywhere, overtired baby, crying at bedtime. Cocoo tracked the naps and showed me we were moving too fast — my baby still needed the third one but shorter. The app gave us a gradual transition plan. Two weeks later we were on 2 solid naps!! Hands down the best baby sleep app that does not more than just tracking!! Highly recommend it!

Such a helpful app 👌🔥

My niece was going through a rough sleep phase, and this app helped us realize her wake windows were off. Once we adjusted her schedule, she started sleeping so much better! It really feels like having a sleep coach with you.
