Week 13
Your Baby’s Development
It’s still fairly early in your pregnancy, but Baby is already capable of quite a lot! If you poke your stomach gently with your finger, she may begin to turn her head toward you; some experts think this may be the beginning of the rooting reflex (looking for a nipple). By now she can put a thumb in her mouth, although her sucking muscles aren’t completely developed yet. And female infants have already accumulated about two million eggs in their ovaries, although this number will naturally drop to one million at birth.
Your baby’s head growth has slowed down; this week, her head makes up about half her body length. By week 21, her head will be about a third the size of her body, and by birth it will only be about a fourth. The fetus, which is now about three inches long and a little more than an ounce in weight, would now fit into your cupped hands.
Here’s what else you can expect this week:
- Tiny ribs will be developing.
- Vocal cords will begin forming.
- Baby’s eyelids will fuse together to protect her delicate eyes.
- Tissues and organs will continue to mature.
- Bone marrow, liver and spleen will be able to produce blood cells now.
- Fingerprints are beginning to form.
Your Development
Welcome to the second trimester, when most women begin to feel much more comfortable than they did in their earlier stages of pregnancy. The side effects of early pregnancy (frequent urination, fatigue, nausea, dizziness) lessen during the second trimester. Your uterus is still small enough so that you can easily go about your daily activities.
At 13 weeks, the uterus starts growing upward into the abdomen, and you may feel some abdominal achiness as the ligaments supporting the uterus stretch. Up until now you may not have gained much weight, but as your baby starts growing rapidly, you’ll see your weight increase respectively.
Even though birth is still months away, your breasts may already have started to make colostrum, the nutrient-rich fluid that will feed Baby for the first few days after birth. As the breasts enlarge, you may notice veins appearing under the skin and the areola enlarging and turning brown. Experts think this darker color around the nipple may be a visual cue for the breastfeeding baby.
You may also start to see the first signs of stretch marks on your abdomen, breasts, hips, or buttocks. (Since stretch marks are partly genetic, you may be able to predict ahead of time whether you’ll experience them or not.) By applying moisturizing creams, you can make your skin more elastic and can help reduce the itchiness that accompanies the development of stretch marks. Creams may also help reduce the severity of the marks, although it’s difficult to prevent them from occurring entirely. The good news is that the marks will be less noticeable after pregnancy, when they’ll probably fade to a more normal skin color.
i was going to post a pic of me, but i haven’t had jerry take one yet and i can’t find the tripod right now. so there will be one soon…
i am out of zofran for maybe a week! i have had an amazingly decent day today, thank the Lord! maybe i am nearing the end of this?! please pray that it’s so!!!
baby bug moves all the time, tho she doesn’t seem to be as active as the boys were, especially josiah. he was crazy!
i am constantly reminded of her presence, and it is wonderful.
happy birthday to my baby brother, who is 26 today. my mom can’t believe her baby is 26!!! jeremiah sang happy birthday to him several times. uncle josh got quite a kick out of that.
jeremiah has a cold (about which he says “i’m cold” lol) and asks to blow his boogies. where he got that, i don’t know! oh, tonight after dinner he said the food all went in his mouth. i said, then it went to your belly. then he said and to my butt next? lol! we’ve been reading that book “everyone poops” (because he likes it, not because he needs it – he goes perfectly in the potty all the time), and it says “everyone eats, so everyone poops” so he knows that food turns into poop.
the boys have been so loving to each other today. it really makes taking care of them a joy. i hate it when they fight and grumble with each other.
josiah is so funny. he wanted to try to learn new words today. he learned “wall” and really tried to say “ceiling” but it sounded NOTHING like ceiling. lol. i can’t believe he’s 18 months old. *sob* can you believe jeremiah was only a month older than that when josiah was born?! i can’t. they are so very different. josiah really doesn’t even “get” that i’m pregnant yet. i need to take time to sing to him about being a big brother…and find the i’m a big brother book too…
when i am feeling ok, i’ve been working on digiscrap pages. i thought i’d share a few with you.
