Reorganising Room For Baby

Hi mummies, I'm expecting my LO in Oct 2021 and cos I stay in a 3 room flat, the other room has been used as a work/storage room. I need to clear it out to make room for the NB and the nanny. But ive heard from old folks you cannot move things out of the house as it affects the unborn baby or something. Is this true? #1stimemom
