My DD was the sameas your little one.
Best sleep was from 8pm-11pm . ANd this is when i would go to bed.
She would feed 2hrs (even over night) until 4 months when i stopped night feeds - still fed 2 hrs during the day.

I just took this as part of the package and lived with no sleep for these 4 months. Perhaps you can rest more during the day - or get DH to take him out of your room at night on the weekend (mattress on the nursery floor) and bottle feed over night so you get 2 nights of good rest a week until bub goes longer?

I would start wrapping again or try co-sleeping?
