I noticed Cala was fussy due to colic, so I asked around and learned about these BioGaia Protectis baby drops (my favorites also include vitamin d but there’s also a version without it!). I researched and they have so much clinical data to back it up that it really gave me a lot of trust to try with her ❤️ Bought these at target, they are super easy to use and I noticed immediate comfort in her 👏🏻👏🏻👏🏻 Ty @BioGaia_USA for an amazing product.*
