Sensory System

Taste & Smell Development

Taste buds and smell receptors develop early, allowing baby to taste amniotic fluid.

📅

Development Timeline

Weeks 8-40

Overview

Your baby's sense of taste and smell develop surprisingly early and are quite sophisticated by birth. Taste buds appear around week 8, and by second trimester, baby is actively tasting amniotic fluid.

Everything you eat affects the flavor of amniotic fluid, exposing baby to different tastes. Studies show babies prefer flavors they experienced in the womb, potentially influencing future food preferences.

Smell develops alongside taste, with receptors forming in the first trimester. After birth, baby can recognize you by smell, helping with bonding and breastfeeding. The senses of taste and smell are closely connected.
