In the first weeks of your baby's life, it is normal for everyday situations to occur, such as medical appointments, shopping, meetings and more, that require your absence from home.
First confirm if you can take your baby with you, perhaps even someone else can accompany you to assist you. You can almost always find a quiet, secluded place to breastfeed. If you can't take your baby with you, you can choose to pump your breast so that someone else can give your baby a bottle during your absence. Extracted breast milk should be handled with great care. You can get a better recommendation from your lactation consultant or pediatrician.
Pumped breast milk can be stored in a clean bottle (glass or plastic) in the refrigerator at +4°C to +6°C (check the temperature with a thermometer) for 2 days. Pumped milk should not be stored in the door compartments, but on the back wall of the refrigerator, where it will stay cooler.
