Hello, My son is 4&1/2 month old. He never latched so I exclusively pum and feed him with bottle. He was underweight when he was born 2.59 kg. From past couple of weeks he is drinking very less milk around 4 feeds and 500-650ml milk and takes long stretch inbetween two feeds. Also he only drinks from his father which is quite frustrating. I was sick hence my husband helped for some time and now my son doesn't want to feed with anyone else. What should I do to solve both these issues.

Hi pumping in long run will tire you out and milk production will also be stopped. Starting feeding directly, it may be very difficult in the beginning but as he gets used to you he will drink from you. Keep him closer to your chest often, let him latch for few minutes.
