Love it...but...

Love the app. It’s great myself and my wife can both have it on our phones, & it will sync up on our phones. However, please make it so we can edit the feeding time. That would make it 5 stars.

No editing ability for feeding

There’s no ability to edit and of the feeding amounts or times if you accidentally hit save! Along with this if you want to enter how many fluid ounces you feed your baby you have to use some super trashy overly sensitive sliding scale that is more annoying than helpful! I’m sure there’s more but this is just what I’ve found in a matter of 2 feedings 🤷🏼‍♂️
