Abstract: A collapsible baby bottle for reducing air-intake during feeding operations includes a body formed from disposable material, a plurality of linear ridges concentrically spanning across a non-uniform circumference thereof, and a coupling threadably attached directly to a top opening of the body. The apparatus further includes a nipple removably attached directly to the coupling, a cap removably affixed directly to the coupling for protecting the nipple from undesirable foreign debris and fluids, and a mechanism for preventing formation of powder formula lumps when mixing the powder formula and water within the body so that a homogenous mixture of the powder formula and the water is obtained. The apparatus further includes a strap tethered directly to the coupling and spaced from the body and the nipple respectively, and a barcode removably affixed directly to a bottom surface of the body for identifying nutritional information about the powder formula.
