Your baby is now weighing in at 3 plus pounds and measuring about 16 inches long, your baby is quickly approaching their birth length.

Your baby is developing their five sense. You baby is now being able to process information, track light and perceive signals from all five senses.

You baby wouldn't be able to smell too much now, even though they likely can smell and taste different foods that you can eat through the amniotic fluid as well as catch a slight smell of the beauty products you use.

Your scent is the very first that they breath and this scent will quickly become their favourite one.

You must be thinking what all does your little one do all this time, they are learning to make faces, hiccupping, swallowing, breathing, pedaling with little hands and feet along the uterine wall and even suck their thumb.
