Each expression visit will start approximately 3 hours after the end of a regular baby feeding session. Each expression visit will start approximately 3 hours after the end of a regular baby feeding session. During each visit, milk will be expressed once a day from each of the two breasts (left & right). During the 4 first visits (at least 1 day apart) Annabella or the control pump will be used. After at least 3 days washout period, milk will be expressed for additional 4 days, once a day from each of the two breasts, using the other breast pump. An expression session will last until no milk is expressed for 3 min continuously but not for longer than 25 min. Participants will be serving as their own control.
