Plz help me with ur valuable suggestion.

Dear Sir/madam, I request you for a second opinion on my baby boy condition, he was born on 32nd week 15 days, his weight during birth was 1.2 and present weight is 1.3 his condition is good now but the problem is with feeding, doctor suggested to feed him 30 ml milk after every 3 hours, but my is able to take only 20ml and keeping the rest of 10ml under cheeks and throwing out, and doc is saying that he needs to be in nicu until he takea proper amount of milk, and this is a very costly hospital they are charging like 7k per day for nicu and doctor charges and I am a very poor guy and unable to afford these charges, my query is, can i take him home if he is taking proper amount of milk every day? Will the baby gain the required temperature himself... Please help me out with your valuable suggestion. Thanks in advance
