Cosleeping

Me & my husband are against cosleeping for numerous reasons. But lately when I'm breastfeeding in the middle of the night in bed, me & my son end up passing out for hours at a time. Seems he'll only sleep at night when its in our bed. Since I'm sleep deprived, I now beg my husband to be on borad with cosleeping. I even mentioned those pillows that the baby sleeps safely in the middle (can't think of the excat name) how else can I convince him. It really is the best night sleeps when he's in bed with us.
