Fetal development in pregnancy week 8:Woohoo! You've got one whole inch of baby inside of you! Your little embryo has finally reached the one-inch mark (30mm). And if it were possible to take a peek, you could actually see your tiny baby without a telescope! What’s more, your baby is finally starting to take on some very distinct human features. For starters, their little tail (really just the spinal cord) has disappeared completely. It’s nice to know your baby can no longer be mistaken for a sea creature! Additionally, both their toes and fingers are prominent with very little, if any, webbing. Upper and lower limbs all show recognizable joints (elbows and knees) and the lower limb bones are starting to ossify. But don’t expect your baby to resemble either parent quite yet. Right now, your baby’s head is disproportionately larger than the rest of their body--making up almost half of your little one’s height and weight!
