Hello. Please excuse brevity/typos as LO doesn't sleep for long!
My DD is 13 weeks old tomorrow. I won't bore you with the horror that was our first 8 or so weeks but eventually we got a silent reflux diagnosis and after moving on from Gaviscon we have been on Ranitidine which has made a huge difference.
My current issue is that:
DD never used to spit up (hence the silent reflux) but she has now started vomiting after most feeds. She is a big eater. To me it looks like a lot but I appreciate that she is keeping most of the feed down. I am just concerned as to why she has started doing this?
Related to this, and my primary concern is that, 3 or 4 times after a night feed I have burped her and put her down to sleep only to wake up about an hour or so later to what can only be described as the most traumatic thing to ever happen to me - my baby thrashing in her basket, fighting and failing to catch a breath, totally choking, gulping for air with a look of pure fear in her eyes and sometimes milk spurting out of her nose. This is HORRIFIC and although I was previously happy with 2/3 hour blocks of sleep (forget about sleeping through - my expectatons have been suitably lowered by reflux).....but I am now terrified to sleep at all in case it happens and I am too tired to hear her.
We have an angel care baby monitor but it never went off. 
This is the scariest thing ever.
Please help - any advice? Has this ever happened to anyone?
My poor baby!
. Yes this is PFB.
