How developed is baby at 33 weeks?
In these last few weeks before delivery, the billions of developed neurons in your baby's brain are helping him or her to learn about the in-utero environment — your baby can listen, feel, and even see somewhat. Your baby’s eyes can detect light and the pupils can constrict and dilate in response to light. Like a newborn, your baby sleeps much of the time and even experiences the rapid eye movement (REM) stage, the sleep stage during which our most vivid dreams occur!
Your baby's lungs are almost completely matured. Fat will continue to be deposited on your baby's body for protection and warmth. Babies gain a good deal of their weight in the final few weeks before birth.
