Just thought that you should keep an eye on the tv programme on Sky channel 254/255 called Baby Whisperer from TRacey Hogg. I was a great fan of her for my first born (who did not suffer from reflux!), there is one of her series which is helping a couple who had twins and one of them suffers from silent reflux.
I just WISH I've seen this programme a year ago when my little Jack (now 1!) was suffering from silent reflux.
I got into tears as I've realised that we do not have the support that we need at the time or a special person coming in our house to show us what we do right and wrong. Although I was a fan of her methods and Jack was my second there were a lot of things which I did naturally to soothe his silent reflux but there was a lot more (now having watched her programme) that I could have done more or better to soothe my little one.
So here you go:
for bottle babies, go and get a variflo bottle which helps the baby to feed slowly (like breastfed babies)
Get a really high wedge with a belt not the standard 25 degrees
Pat your baby, arms up your shoulders, making the ssshu noise and no moving around the house/room (this I knew that more moving around used to unsettle more Jack but she proved me even more that it was the right thing to do!) Just a good smooth, gentle patting on his/her back.
Keep your baby upright all the time and even when you change him/her
Try to get hold of this programme as I REALLY TRULY believe that it will give you good tips!
