Why people love SleepWellBaby

“SleepWellBaby has been an absolute life saver! The easy to follow time zones and wisdom made me feel more confident as a first-time mum. With tracking sleeps and feeds you can easily see patterns starting to form with the program. You can share all of this with your partner, grandparents or childcare provider. Everyone can follow along with your little one.
Tiahn, Mother of 5 month-old daughter

“The app contains so much helpful information, presented in an easy to absorb format for the sleep deprived (most new parents!). There's so much unsound and unhelpful advice out there for baby routines and sleep, but I trust Tresillian to be based on developmental science and respectfully guide us to understand our baby's universal and unique needs.”
Ruby, Mother of two. 5 months and 2 years

Best app to monitor trends

Really nice graphs to see trends for sleeping and eating habits. I found it particularly useful to start seeing my sons routine development. One thing I don’t like about the app is being unable to track diapers and also you can’t select which breast you’ve fed on to keep track of that. There is however a noted section for each feeding session that you can write this all in. Overall, I really recommend the app especially if you want to monitor your baby’s developing routine

So helpful

I have been struggling to settle my baby and understand his ‘routine’. I have been using this app to track his normal/natural feeding (demand fed) and sleeping to draw pattens in the progress section. This has allowed me to observe his natural routine and progressively move him onto a daily routine to reflect what he would do naturally. The settling techniques are a goal for me and I’m trying to get there gently which is encouraged. If you are looking for something to guide you without being strict and the ability to track your babies sleep and feeding this app is great.

Highly recommend this app to anyone who is having difficulties with sleep, both baby and mother.

My first born was a shocker and wish I had of done something sooner. He is almost 5 and has now only started sleeping in his own bed.
My now 14mth old was waking numerous times through the night and didn’t want another 4 years of no sleep. So went straight to the experts. It only took about 3-4 nights and she is now sleeping through the night. Routine is the key!
