Hi Rubymum,
Poor baby and you too
Must be horrible seeing your baby in pain and I imagine neither of you has very restful nights.
Definitely get a higher wedge! Get the one with a 'dip' into it for his body so there's no chance he will fall out if he is wriggling alot. There is of course a belt aswell. I found these wedges really helpful. Even after keeping baby upright for a longlong time after feeding it's nice for them to be put down for sleep/rest at this angle.
Keep baby upright for a long time after feeding. If you are feeding in bed at night and are holding him upright, do get a bedside guard just to be safe and in case you fall asleep..
I'm not qualified to give any medical advice but Ive worked in families that has been given medicine for just silent-reflux (I was baby's night nanny) that was ment for 1 year plus babies but te medicine was given in less dose and only in small granules that I pit on the top of my finger and rubbed on baby's tounge. Could always ask your Pead about this?
All ideas I have for now!
Hope you get some sleep tonight!!
