Pre-Natal Development
Growth of the baby from conception to birth 40 weeks, 10 months, 280 days, 3 trimesters.
Very rapid: goes from the size of a pencil dot (one cell) to a 7 ½ pound (200 billion cells) in 9 months. 4 weeks = poppy seed, 5 weeks = grain of rice, 7 weeks
= blueberry, 14 weeks = apple, 15 weeks = orange, 39 weeks = watermelon
If this rate of growth continued past birth, the baby would weigh 160 lbs by its first birthday.

3 Trimesters (about 13 weeks each)
• 1st Trimester – focus is on physical
development– Define ovum, sperm,
conception/fertilization– The greatest time of risk and
vulnerability for birth defects to the developing fetus.
• 2nd Trimester – Increased organ development – Define Quickening and Lanugo– Physically the easiest on the
Mom
• 3rd Trimester – Continues to grow and
practice using body and bodily functions
