I know it's hard hun, the exhaustion really gets to you and it's especially hard when naps are short so you don't get a break. I really don't think 2 NF at this age is unreasonable though, and again the 5:30am WU is after an 11hr night, so I'm not sure much can be done there unfortunately. He's around 14/15 weeks now? I think I was a little off on his age before, I would try a 1.45hr A time as you are probably starting to get close to the 4hr EASY - I found once DD was on a solid 2hr A time her naps really improved, but for DS it was unfortunately after the 3-2 and was more like 6/7 months.
