Senses in the womb


I found out today that babies can taste and smell in the womb! Amazing!

Here are the facts:

Taste:

By 13 to 15 weeks a fetus's taste buds already look like a mature adults, and the amniotic fluid that surrounds the fetus can smell strongly of curry, cumin, garlic, onion, or other strong tastes from a mother's diet. Studies show that a fetus's swallowing increases when surrounded by sweet tastes and decreases with bitter and sour tastes. (I guess I should eat more chocolate? Haha!)

By birth, babies have a strong sense of taste. Newborns can discriminate between tastes and have shown definite taste preferences. Even preemies as young as 33 weeks suck harder on a sweetened nipple than on a plain rubber one.

Smell:

A fetus's nose develops between 11 and 15 weeks. Until recently, scientists didn't believe that fetuses would have any sense of smell, since it was assumed that smelling depended on air and breathing. However, the latest research has opened up a new world of possibilities.

The nasal system is made up of no less than four subsystems, and it's now believed that the amniotic fluid surrounding the fetus passes through the baby's oral and nasal cavities, triggering these senses.
