Oh Hon, there is nothing wrong about that thinking! If cosleeping is a solution which doesn't bother you and she sleeps better, that's a food choice. Remember it's about you and your child to feel good, not about millions of others opinions!
However I start to think that her NW probably has a different route then hunger honey. Is she ill, some teething involved? Would you consider opening a thread on sleep board so some nice ladies could share some advice?
