Ok, long story alert but we got admitted into hospital last night as he continued not eating or sleeping and just screaming and i stayed with him, tonight ive come home to get some rest and DH is staying with him at the hospital. Here is what they think the issue is:

Reflux not controlled properly
Cows Milk Protein Intolerance
Food Aversion due to reflux, gagging and choking and upset tummy and also due to us being so anxious to get him to feed we were somewhat forcing him to take the bottle when he didnt want it.

All these things made for bad experiences for feeding for him so he would just scream whenever he saw the bottle. However we started being very gentle with him and not forcing him, if he didnt want to eat then we wouldnt push it, he had started losing a little bit of weight and they said if he continued not to eat they would have to feed him by the tube through his nose. They were very thorough and checked EVERYTHING to make sure it wasnt something they had missed, they even stuck a needle into his bladder to get a urine sample (oh my gosh i just cried and cried as he screamed in agony and those big blue eyes looked at me with intense fear!)

They want him to demand feed for a few days so he is asking for the bottle rather than having it shoved in his face, however we have had HUGE success today. Yesterday he took 100mls all day and today he has had feeds of 90mls, 120mls, 150mls. 120mls and 200mls!!!!! He seems much happier and had alot of good sleep today. They have prescribed him liquid Losec for his reflux and should everything continue to improve then he comes home tomorrow..

Im also booked in to see a pediatrician on Tuesday

Im exhausted.... and all alone in my house without my boy for the first time ever... strange feeling...
