He is swaddled and I've gotten the room as dark as possible without buying blackout shades. He has a paci but really doesn't like it that much and can't seem to keep it in by himself. When he does take it, he wakes immediately if it falls out and cries, so I can easily see it becoming a prop. He has reflux so I propped his mattress up. He has been on Zantac for almost 2 weeks and it is helping so much! I'm wondering if that is still the problem though. Maybe he just needs to be on it longer? In the past few days he has been able to resettle and fall back asleep several times (which is a major improvement), but he is still waking at the end of each sleep cycle.
