Hi,
He sounds a lot like my ds!! (including the reflux) And mine takes a paci too, I think you will find MANY on these boards do, I don't plan to wean it until 3 yo!
We have actually been going through something a little similar which I've posted about too, and I have suspected he is having nightmares or night terrors. However in your case and due to his age I'm wondering if he could be going through SA. Have you considered this?
In your shoes I would probably try W2S to deal with his NWs. There is more info in the faq's or let me know if you have questions about it, I've done it quite a few times successfully. xxx
