Hi Rachel, my DS will be 3yrs. at the end of April and we are having NW issues as well, for the past 5 months. He will ocassionally nap on the couch, but not every day. I also have a 4 month old. My oldest, Kyle gave up naps 3 weeks before I had my youngest Eric. Kyle would wake several times in the middle of the night starting around 11PM, sometimes 1AM . It would go on for hours and he would be awake for as long as 3 fhours with us putting him back in his room. I have had some behavior problems with Kyle, but usually not. My husband has many behavior problems when dealing with him. I know how you feel. It's exhausting !!!! We've been doing Melatonin, an herbal sleep aid, 30 mins. before bed and it has seemed to help. However, we have also resorted to using an allergy med too. Not Benadryl, that did nothing for him. He's still getting up at 4AM, but not for as long and then waking around 6 or so. It's better, but not great. At this point we're taking what we can get. I hope things improve for you.
