7 weeks

• Elbows form - Again, taking a peek inside you could see your baby's fascination with bending and flexing. Later you will swear you can enlist your child as the star of the next "Karate Kid" movie!
• Fingers start to develop - These digits often become your baby's first toy!
• Feet start to appear with tiny notches for the toes - It is fascinating that at less than a half inch, your little guy (or gal) already is leaving "footprints" on your heart!
• Ears eyes and nose start to appear - Although they may resemble an alien life form, these all "shift" soon enough into a more normal appearance.
• Intestines start to form in the umbilical cord - Did you know that initially the intestines are not formed inside your baby's body?
• Teeth begin to develop under the gums - Thankfully, right now you won't be dealing with teething pain!

Your Baby

• This week your baby's brain is growing at a mind-boggling 100 cells per minute within a see-through skull. If you could peer inside, you'd see those tiny brain cells growing and growing and growing (about as quickly as you feel like yours are shrinking and shrinking and shrinking with your "pregnancy brain"!). More high points include:

• Your baby's face is becoming more defined this week. A tiny mouth hole (which will be ready to wail before you know it!), tongue, nostrils and ear indentations are visible. His or her eyes are wide open, but he doesn't have irises (the colored part) yet.

• Baby's arm buds are growing. At this point they look more like microscopic ping-pong paddles than arms. Baby's leg buds are also forming and will look like tiny paddles by the end of the week.

• The umbilical cord—the connection between your baby and the placenta—is now visible.

• Your baby is now between 1/3 and 1/4 inch long—about the length of a Tic Tac and about as heavy as an eyelash. While that sounds tiny, he or she is approximately 10,000 times bigger than at conception. Crazy, huh?

Pregnancy Week 7: All About Baby

Your baby-to-be has been busy this week. His brain is continuing to develop. The circulatory system becomes more complex as lungs begin to form.
During your 7th week of pregnancy, Baby's face is taking shape with his eyes showing some pigmentation, visible ear holes, miniscule nostrils, and an indentation where his mouth will appear. His digestive system and stomach are starting to form. His arms and legs are growing, but his fingers and toes have not yet developed.

How Big Is Baby?

This week, Baby is about the size of a blueberry!
