Enable a way to share data with partner?
My husband and I share care of our little boy so it would be really helpful to be able to share the data by message or to have 2 apps that synchronise on two different devices?

This is already possible!
To synchronize a baby with a caregiver/partner:
You need to:
Go to settings and tap the baby you would like to share. Enter the email address of the caregiver/partner then tap Done. The caregiver/partner will be sent an email requesting they download BabyTime and signup.
Then the caregiver/partner needs to:
Download BabyTime from the App Store
Signup, ensuring that the email address entered is exactly the same as the one you nominated (
Once the caregiver successfully signs up, the baby will appear along with all logged activities. It make take some time for this initial synchronization to occur.
