M.L.
Have you tried putting her crib next to your bed and having her sleep there without the side up and then she's in a side car position? She can still sleep next to you and nurse as needed, but she's in her own space instead of between you and your husband.
My oldest started sleeping through the night on her own at about 18 months. So, if you're willing to wait it out a little longer, she might change things up on her own.
