I know Tula isn't really recommended for newborns, except if with an infant insert which may cost an additional penny. Can anyone recommend a baby carrier that's safe from birth to toddlerhood?

Boba 4g has an integrated infant insert included when you purchased it, however, the minimum weight requirement is 7lbs. The maximum weight is 45lbs. You can check this page for more information: http://www.boba.com/support/boba-carrier/the-newborn-hold
