could you get a toddler bed hon?
Tank would sleep easily in our bed and his cot but hated the sight of his big boy bed (normal single) so we bought a toddle bed and he loved it. We began day sleeps in it and slowly progressed in a matter of week or 2 to night sleeps but it worked.

I cant comment on dream feeding...maybe give her sepcial baby of her own (it worked well for us with mini me), she now cuddles her baby to sleep every night
