Do I need to purchase the entire nfant® Thrive System to use the nfant Bottle?

Yes. Although we sell individual nfant Bottles, these are intended as replacements or extras and cannot be used without the nfant® Thrive Bottle or the nfant® Thrive Tracker App to record or get feeding data. nfant® Thrive Bottle is a complete starter kit and includes all of the components you need: Two nfant Bottles, a Bottle Sensor, charger and assortment of nipples at various flow rates. Additionally, you will need to download the nfant® Tracker App which will be soon available for free download at the Apple App Store or Google Play.
