Your baby’s growth: Lung development, balance & touch
Your baby still has a lot of growing to do. At 1.2 pounds and 8 to 9 inches, she should add at least another 5 pounds before birth for optimum health.
This week she prepares herself for a big cry upon arrival. Her lungs begin to produce surfactant, a wetting agent that will help her breathe correctly and keep her tiny lungs from collapsing or sticking together. Blood vessels and air sacs are developing in the lungs and will eventually exchange oxygen and circulate it to all parts of your baby’s body.
This week the following developments may occur:
- Inner ear. This will become fully formed. Controlling balance, the inner ear means that your baby may be able to tell when she is upside down or right side up while floating in the amniotic fluid.
- Touch. She will continue to explore her internal environment, flexing her fingers and touching her surroundings.
We are happy to be celebrating baby girl’s V-day today! V is for viability. Babies born after the 24th week have a much better chance of survival if the mother were to go into pre-term labor. We definitely want her to incubate a lot longer but it’s a good feeling to have made it this far.
We leave tonight to fly out to my dad’s for the weekend. I’m looking forward to some outside dining 🙂
