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

"5 stars! Most baby tracking apps simply do that - track. But what differs here is that you are 'tracking' against a plan to work towards results. The encouraging pop-ups are really helpful as are the daily check-ins. A holistic view of baby's progress... Highly recommended"

“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

Our sleep and settling programs are designed by experts for your baby’s age and stage and include full access to our suite of tracking tools and resources. Choose the program that’s right for you.

Simple, helpful and great features

Highly recommend to any parent dealing with frequent wakings. Simple to use and self care features like rating how your progressing as a parent / caregiver each day is an absolute win and unique to other apps. Day 7 and we’ve finally got my Daughter whos been co-sleeping with us (since 5 months) to finally transition into her cot. Still some way to go but a great way to start moving in that direction. There were a couple of times the app froze and I had to open and close. Often when the timer was on and found it difficult making notes at the bottom for the night sleep but no other issues. A job well done!

Simple and easy to make appt to talk to nurse

Downloaded this months ago but didn’t really use it. Got it again last week as sleep was still terrible and I stumbled on the feature to make an appt to have video chat with a tresillian nurse - I booked this at 2am for 11am the next day! Was great to be able to do it when I was concerned. Super easy and the technology was easy. The advice from the nurse (Meredith) was simple, thoughtful and non-judgemental and I’ve been using the app to track sleep since, which has been handy.
Great app.

Latest update is buggy

Most recent update has totally wrecked the app. Detailed feed timer no longer works and instead of saving your times when it’s paused, it randomly resets itself to 20/30 seconds. Very annoying and bug report submitted a week ago with no fix available on the App Store yet. Constant surveys when you open the app is annoying when you’re trying to quickly check information and the nappy tracking feature has been ‘coming soon’ for months and months; at this rate it would be better to get rid of that tile since it looks like it’s never coming. The app was useful for timing feeds and sleep but now the detailed feed timer is so buggy I’m not sure how long I’ll continue using it.

Hi there, thanks for taking the time to review the app, sorry to hear you haven't had a good experience with the latest version. We did have some issues with the new release, in particular with the tracker, as a result of some changes from Apple that impacted us - I'm very sorry for that. We have since resolved these issues - if you restart / open the app fresh you will have the latest version available (these changes didn't need a new update from Apple). We hear you on the surveys - the daily checkin can be skipped and we now only show it between 9-5. The 7 day reoccurring survey can now also be skipped should you want to - these surveys are in place to ensure we monitor the health and wellbeing of the parent and baby to provide targeted help. We have designed up the nappy tracking and it is ready to go into development - we have just been having a difficult time prioritising it over other features / tasks - we have a small team so it is a challenge. I'm more than happy to share with you how the feature will work and let you know as soon as it is ready if you want to - just send over your details to and I'd be happy to share :) Thanks again for reaching out to let us know your experience - regardless of whether or not you continue to use the app, best of luck to you and your little one! Kind Regards, Daniel - CTO
