Baby senses

I thought this was kind of interesting and thought I would share it with any of you who may be interested as well!

Touch

Touch is the first sense she’ll develop - studies have shown embryos respond to a gentle touch on the cheek as early as eight weeks. By 11 weeks, she can feel touch on her palms, by 12 weeks on her soles and by 17 weeks, most parts of her abdomen and buttocks are sensitive to touch.
By 32 weeks nearly every part of her body can feel pain and temperature, and your baby is exploring the world around her by using touch. She may also explore her own hands and face, and suck her thumb to see what it feels like.
Smell
The first of her smell receptors appear between five and 11 weeks after conception. Her nose, which develops between 11 and 15 weeks, is continually filled with amniotic fluid, which can carry the smells of your food.
Research has shown premature babies born as early as 26 weeks respond to different smells. It is her sense of smell that helps guide your baby to your breast for her first feed after birth.
Taste
Your baby’s taste buds begin to develop in weeks 12 and 13. By 30 weeks the surface of her tongue is full of hills and clefts containing taste buds. Scans have shown unborn babies can stick their tongue out to taste the amniotic fluid that surrounds them.
It carries the flavour of strong foods that you’ve eaten and will give her an early taste for dietary preferences later in life. Just like smell, her sense of taste will encourage her to take her first sips of breast milk once she’s born.
Sound
Your baby’s ears will be structurally complete by 24 weeks and the first sounds she’ll hear will be the gurgles made by your body. She’ll also be able to hear sounds from outside the womb, such as conversations, and loud music, but they will be distorted and muffled.
She’ll learn to recognise your voice as this will travel through your body directly to her and research shows that she is calmed by hearing you speaking.
Sight
Your baby’s eyes are fully formed halfway through your pregnancy (20 weeks), but sight is the last sense to develop. Her eyes will remain closed until 26 weeks, and after this she starts opening and closing them to develop her blinking reflex.
By 28 weeks her eyes are sensitive to light and she may be able to detect a slight glow from very bright sunlight shining on your bump, but her ability to focus and perception of colours won’t develop completely until after she has entered her new world.
At birth she can focus from eight to 12 inches, which is about the distance to your face when you’re breastfeeding her.
