WEEK 31: Baby developed all six senses

Brace yourself for some good news—all your baby’s senses are fully developed when you’re 31 weeks pregnant. In addition, your baby is also getting smarter, but you may feel a bit absent minded at times.

With regards to size, your baby is similar to a bunch of asparagus, coconut or cucumber, and is most probably taking over your lungs, so you may at times feel the need to catch your breath even when you walk up a flight of stairs.
