Baby avatar edit

Installed Carrierwave gem and shows image avatar on Baby's profile page.
Images convert to PNG
Image for thumbnail is resized to 200px
Border radius creates circle avatar

Quick note. You deleted the profile attribute of babies, and you correctly added a column for the new field, but I think it would be better to either rename profile_pic into avatar, or delete profile_pic and add avatar. Choose one or the other, but it can't be that profile pic is still in the schema
