Susu Drop

Hello all, just sharing my feeling.. A bit down bila susu start drop yesterday.. No LDR at all, 30 mins pump.. Dapat dalam around 2 or 3oz only. Before 5 to 7 oz.. Baby tak boleh nak makan susu fresh sebab x cukup untuk dia.. Demand baby 4 to 5 oz, baby 8 months old. Not sure is it because spare parts pump dah lama x tukar (tak pernah tukar since Jun 2019) or saya yang stress..
