Born with 2.2kg and he is not drinking properly

Hi how old is your baby now? Does he have jaundice? The first few days will be very tough but it will get easier soon. Try to latch as much as possible. I also had to feed my baby by syringe but it was very inefficient. The nurse taught me to put a finger next to the tip of syringe (make sure your hand is clean), as baby starts sucking your finger you can pump the milk. This is to teach baby to suck. All the best.
