One massive flaw sharing your baby profile
Having your baby profile on multiple devices does not work. What happens is that when you enter new events on your timeline the master record for that event is on the device you enter it on. If for any reason you lose that device or lose the application on that device, all of that data is lost. this scenario particularly showed up installing the application on both parents iPhones and also having it installed on an iPad. This three-way synchronisation would regularly freeze and they would be missing items on one or other of the devices. If you fix the missing event on one device you end up with duplicates what other devices. Synchronisation problems give rise to data loss, data, corruption and generally and mind the entire use of the application.
