He is a good weight hun so at least isn't failing to thrive
His reflux could partly to do with him being premature as the eosophogus flap isn't working properly when they are born (as I understand it).
Damien had small amounts every couple of hours too but his reflux just made him sick no matter what he had. He is now fed 4 hourly and has been for the last 2 months. We changed his milk many times, to Soya, to different brands of normal first milk (Aptimil, Farleys, C+G, SMA Gold) but none of them helped. He is now on Omneo Comfort (made by Cow+Gate) and it has improved his sickness and unsettledness no end.
My HV is not very helpful and neither is the doctor, because really they aren't paediatritions (sp?) and they aren't very clued up about premature babies at all. They only deal with 'normal' children.
Omneo Comfort is a thickened feed so it's harder for them to bring up and stays in their tummy. Makes their poo smell like rotten eggs but I can live with that if he keeps his milk down! When he is sick he only brings up watery vomit which shows the milk is staying down.
He is also on liquid suspension medication for his reflux (Domperidone and Ranitidine). He is having a PH study (a probe from his nose into his tummy) today to determine whether these medications are making any improvement on his condition or not, and will also show the severity of his reflux.
Does your son see a paediatrition? Maybe your Gp could refer you to see one if you don't? One thing I have leant with GP's and HV's - you have to SHOUT to get anywhere with them and get the tests you need. It was only after my son went into hospital because of his reflux that they listened to me.
Another thing thery can give you to thicken up the feeds in Infant Gaviscon (poder sachets - which in my experience didn't help us) but it does work for some babies. With Omneo Comfort or if you use gaviscon in normal first milk (you can't use Omneo and gaviscon together) you will need to get teats with bigger holes. Damien uses Dr Brown bottles with level 3 teats (or fast flow if you use normal bottles).
Although Damien has this aswell as your son, I can't give direct advice that you should follow as I am not qualified to tell you, but this is what works and doesn't work for us and things you can discuss with your HV to do.
Sorry for rambling on!
