Facts 23 to 25

“Is our baby developing normally?”, “Who will our baby look like?”, “How will our older child react?” Here are 25 facts about pregnancy to help guide you through this period.

Do you want to know more about your pregnancy? Make the most of the Internet! For example, you can sign up for a personalized newsletter from Naître et grandir that sends you information every week related to your stage of pregnancy or to your child up to 5 years old. “I’ve been signed up since the start of my first pregnancy,” says Véronique, who is now expecting her second child. “For the baby on the way, it tells me which organs are forming and when. For my 18-month-old son, it gives me ideas on age-appropriate activities I can do with him.” On our website you will also find an entire section with our Features in English.

Upon conception, the embryo already has the two chromosomes that will determine the sex. If the embryo has two X chromosomes, it will be a girl. If it has the X and Y pair of chromosomes, it will be a boy. However, it’s only at the 8th week of pregnancy that these chromosomes enter into action to actually define the sex. At the end of week 12, the foetus’ reproductive system and genital organs are completely formed. So, is it a girl or a boy? Some couples prefer to keep it a surprise while others ask to know at the ultrasound. On average there are 105 boys born for every 100 girls.

“My sister used to have a lot of nightmares when she was pregnant. Not me. But since the 6th month of my pregnancy, I’ve been waking up at five in the morning and can’t fall back asleep,” says Véronique, who is pregnant with her second child. Like Véronique, many women sleep poorly during pregnancy, especially during the first and last trimesters. At the beginning, the production of hormones makes women feel more tired. Then, as the baby grows, sleep can become uncomfortable or disturbed due to the frequent need to pee (the baby pushing on your bladder), back pains or leg cramps. Towards the end of the pregnancy, most women wake up an average of three times per night.


  • Physical changes due to the pregnancy, the effects of hormones and the new baby’s arrival all cause couples to experience a wide range of emotions.
  • Pregnancy is a good time to start building a relationship with your unborn child.
  • It’s normal to have fears and a lot of questions.
  • Doctors, midwives, nurses, prenatal classes, books and reference sites that talk about pregnancy are all good sources of information.
