Baby's eyes are working

Thanks to those developing facial muscles, your baby is capable of making a few expressive frowns and squints, even at this early stage.

Baby's beautiful eyes are finally working too, making small side-to-side movements and perceiving light, although the eyelids are still sealed. Peekaboo!

Baby's skin is transparent

Your fetus is becoming a looker too — with a face that's starting to look more human — but a skinny looker, since there's no baby fat yet.

And here's the skinny on baby skin: It's practically translucent now, so if you took a peek inside your uterus, you'd be able to see your baby's blood vessels under that thin skin.

Baby will soon hear your voice

Listen up: Tiny bones in your fetus' ears are in place, making it likely that baby will soon be able to hear your voice (or something like it) when you're speaking. Generally, babies fully develop the ability to hear in the womb by 18 weeks of pregnancy.

In fact, studies have found that babies who hear a song while they're in the womb recognize the same tune when it's sung to them after they’re born — so choose your lullabies with that in mind.

The Mutlu Anne app is with you every step of the way on your pregnancy journey.

Thanks for reading.
