I only pump all milk and feed to him in bottles since I back to work (becasue he is lazy to 啜啜埋身餵 since he was 2 months), But I still 堅持 mama milk is better than powder, so I pump all to him in bottle la. Keeping the supply of milk, also 堅持pumping the milk in every mid-night - 2 or 3 O'clock, after his 2.5months and dont need to feed 夜奶 any more), even it is too hard, but we see our boy, we think it is worth.
