A pump-activated feeding container having a handheld container body with a removable top and a flexible straw assembly disposed within the body and exposed outside of the body. The container includes a priming bulb pump assembly directly coupled to at least one of the container body and container top in a watertight configuration and with a flexible and elastically deformable membrane defining a membrane cavity. The membrane is operably configured to have a membrane depression translation path 306 inducing a pressurized flow of liquid through a second enclosed straw channel of the straw assembly and an upper straw opening and to have a membrane release translation path 400 inducing a vacuum and flow of liquid through a first enclosed straw channel of the straw assembly and an upper straw opening.
