"body": "Where to begin with why I like this app so much? Super helpful that it can be updated by multiple devices, I’m easily able to log nursing, sleep, diaper changes, etc, with as much detail as I desire, all in an incredibly cute interface with fun graphics. The data visualization is well thought out and the UI is intuitive to interact with. Any time I think of something new I want to use the app for, the function is already there and more! For instance, I just discovered the iPhone widget this morning and my experience has been further elevated yet again. It is PURE JOY to use, both as a former UX/UI designer and a first time parent. I’m so glad I found this and will definitely recommend to all my friends.",

From tracking feeding schedules, diaper changes, and sleep patterns to offering growth milestones and visualizations, this app covers it all. It's user-friendly, intuitive, and has simplified the overwhelming task of managing my baby's daily routine. With its convenient features like a feeding tracker, sleep monitoring, and growth tracking, along with seamless synchronization across devices, this app has become an invaluable companion. I highly recommend this fantastic baby tracker app to all parents—it's a game-changer that will undoubtedly make their lives easier and more enjoyable.",

"body": "I rarely rate apps, but once in a while I find one that does exactly what I need it to do and it does it well. Though the interface is a little cartoon-y, the layout and functionality is excellent and my less-than-tech-expert wife mastered it almost instantly. For new parents, this lets you record all sorts of information that you find out you may need to tell the pedestrian The customization is good (but I wish it transferred across devices, instead of having to set it on each one) Working across devices was a critical need as my wife and I have this app on four of them, because we don’t know which of us will have data to enter or when. It updates fast, too. The nursing timer is really good and much more useful than just using the basic stopwatch It has the little ads which don’t really get in the way, but I would pay for an app that helps me as much as this one does if I could get rid if the ads. On the phones they take up a higher amount of screen real estate, but on iPads you hardly notice them.",

"title": "Only missing one thing!",
"body": "This app is very helpful and easy to use. It is great for tracking expected and normal events and does have “activity” tabs for illnesses BUT there is only the one generic “other” option. When using the app, there are a couple of other things we track regularly with newborns and it would be great if we could make a tab for events that we track over and over, such as tummy time and, more importantly, spitting up or reflux events. As a pediatrician, that can be very helpful data when parents ask about it in the office and if it’s own tab could be made it would be much easier to track events of reflux that don’t involve spit up as well, which are harder to see/remember but just as indicative of the problem. In short, being able to add tabs for specific things would be so helpful!",

I love that me and my partner can both use it on our phones when each is taking a turn with baby. We also add a new photo everyday which is fun. This was extremely helpful in the beginning when we were tracking how many diapers he was going thru. Found out he wasn’t producing enough and we needed to supplement with formula. You can also see patterns of sleep with the graphs and that’s super helpful to start a sleep routine. Can’t recommend this app enough",
