We describe length and time rescaling across the paraelectric to ferroelectric phase transition in BaTiO3. Small ferroelectric clusters are unable to grow in the paraelectric phase and exist for a short period of time only. The onset of the phase transition invokes a rescaling of both size and time lenghts as necessary ingredients for ferroelectricity to come into existence. The growing of ferroelectric domains involves correlated chains of Ti-O dipoles, which causes domain wall rigidity and domain shape stability. Ferroelectric nanodomains may host islands of opposite polarization (antiferroelectric defects), which appear as an intrinsic feature of the growing BaTiO3 ferroelectric material
