Congratulations on the birth of your son.
I agree with a lot of previous posts - DD1 was born at 32 weeks and we were told to expect to bring her home around her due date. She had a Grade 3 brain bleed and all sorts of other issues... including jaundice, NG tube only for first 9 days...
On day 23 they told me that the parents' room was available that night and, if I stayed in, then she could come home the following day.
There had been absolutely NO warning - we were still only in the 'second nursery' and had been told that she would basically work her way towards the door before coming home! She was still wired up to the monitors until 3 hours prior to us bringing her home!
DD1 is now a fabulously wonderful 4 year old and you would never know she had such a hard start in life.
On the other hand, DD2 was born (almost) 2 years ago at 35 weeks - on Christmas Eve. Obviously she was in NICU for Christmas - and the following 10 days as she struggled to gain weight. However, the staff were fabulous, Santa still found her (which means she had some gifts as we had bought her nothing as she was not sue until the end of January!) There were some lovely gifts from the staff and we have donated gifts this year for the babies in NICU over Christmas.
Again, she is a fabulously wonderful little rascal now and we are looking forward to what is her 3rd Christmas - even though she will be exactly 2 years old!
Hopefully, your DS will come home, and the doctors do err on the side of caution. But, if he needs to still be in hospital then that really is the best place for him.
Also, with regards to the nurses persevering with the bottles and just putting the feed down the NG tube; we had issues with DD1 where we would often turn up to do cares to find they had been done (to group her tests and disturbances). Either get your DP or a MW to speak to them - I found that they are very focussed on getting your baby medically sound and this can mean that they focus less on the parents.
Also do not be afraid of practically moving in so that you are there and can do as much for him yourself. I discharged myself after 2 days with DD1 but was still at the hospital for 12 hours each day if I wanted to be - I became a fixture and no one ever had a problem with that. I second Kangaroo care to speed things up, and also because it is lovely! DD1 could hardly come out of her incubator for the first 9 days but we still managed several 10 minute slots each day.
Good luck
