My husband and I are at our wits’ end

My four year old has autism and is a terrible sleeper. I know the two can go hand in hand but it’s beginning to become detrimental to the family, physically and emotionally.We’ve tried sleep meds and melatonin (per doctor recommendation), we’ve tried a night light, white noise, weighted blanket, a weighted vest, black out curtains, a fan, body pillows.....I feel like there’s nothing left to try.He takes over an hour to fall asleep, and refuses to go to bed without someone laying with him. Attempts to get him in bed alone result in full blown meltdowns. With a three year old and a 9 month old also in the house, the cry it out method really isn’t an option.Like clockwork he wakes up between 0030 and 0100 and comes into our room because he’s realized he’s alone again. My husband always takes him back, as I still wake up at night to nurse the baby. Some nights he’s able to go back to sleep right away. Some nights, it’ll take him three hours. Which then screws the mornings up trying to get him out of bed and ready for school.My husband and I are beyond exhausted. As a stay at home mom, my patience is a tad better than my husband’s, but I think he’s starting to resent our son. We know it’s not his fault but there’s only so little sleep one can take. It seems like my husband is constantly irritated and his fuse is incredibly short. Everything about the situation gets him riled.I’m just looking for help. Maybe something we haven’t tried yet. Anyone who’s on the spectrum, or has a child on the spectrum that can offer some experienced advice? via /r/Parenting http://bit.ly/2R4POtv
