Child Brain Development

It covers the entire journey right from before conceiving, the pregnancy phase and the lactating phase of a mother.

Change the title from Child Brain development to Sensorial development in the womb’
A fetus develops a variety of senses in the womb, including touch, taste, smell, and hearing:

Touch
The first sense to develop, with receptors forming in the face as early as 8 weeks into pregnancy. By 12 weeks, touch receptors are developing on the palms and soles, and by 17 weeks, they are developing on the abdomen. By 32 weeks, the fetus has a sense of touch that is sensitive enough to feel a single hair brushing against its body. 
Taste
Taste buds mature as early as 13 weeks, and fetuses may develop a preference for sweet tastes. 
Smell
The sense of smell begins to work from around 16 weeks into pregnancy. 
Hearing
Studies on prenatal auditory learning have focused on the development of the auditory system. 
Light
Although it is dark in the womb, human skin allows some light to pass through, which may provide some illumination for the fetus. 

The development of sensory functions in the womb helps prepare the fetus for life after birth. For example, the ability of newborns to recognize their parents and their native language is a result of the sensory development that takes place in the womb.
