Watch Your Baby's Growth
Here's to hoping you're no longer feeling nauseated or exhausted! Right now your baby's brain and eyes are making dramatic strides each day. Learn all about it.
Your Changing Body
Got butterflies in your belly? It could very well be your baby kicking! Most moms-to-be experience this major pregnancy milestone between their 16th and 20th weeks, but don't expect any big karate chops just yet.
Your Developing Baby
Your baby's delicate skeleton continues to harden from rubbery cartilage to bone. Even so, his bones will remain somewhat flexible for an easier trip through the birth canal. The umbilical cord has fully matured with one vein and two arteries that are protected by Wharton's jelly.
Tip of the Week
Even if you didn't experience constipation in the first trimester, you could experience it now as the hormone progesterone relaxes smooth muscle tissue throughout your body including your gastrointestinal tract which slows down digestion and also leads to gas, bloating, and burping. In fact, constipation affects about half of all pregnant women.
Your Week 16 To-Do List
