Love this app. Have literally used it from the day our baby was born to track her feedings and diapers. She was severely jaundice so it was important for us to track. Now were sleep training, becoming an even more useful tool for our purposes. Love that growth can be recorded as well. Two suggestions: 1): just integrate the sleep app with this one, or make the more "advanced sleep tracking" in-app purchase. I downloaded this companies advance sleep tracking app and I hate having two apps for one need (company mustve taken a page from Facebooks offering if a separate messenger app... I digress). I ended up deleting the app and just using the sleep tracker in this app. I just make any sleep related notes in my iPhones notepad. Too bad for me that you already got my $2 for that one. 2): the growth chart always crashes the app whenever I try to switch to view weight.
