Your active little kick-boxer is now around 2.7 kilograms (about 6 pounds), and you’re probably feeling every ounce of that weight in your pelvis. The soft layer of lanugo hair that once covered your baby’s body is shedding, and they’re also losing some of their vernix (though don’t be surprised if your newborn still arrives with plenty of it on their skin).
Your baby’s brain growth is now racing ahead—it’s about a quarter of the size of an adult’s and will triple in weight during the first year! Their lungs are ready to breathe air, though their digestive system still needs time to mature. Don’t worry—colostrum (the thick, yellowish first milk your breasts produce) is the perfect food for this stage. Colostrum literally coats your baby’s intestines with illness-fighting antibodies and is so packed with protective white blood cells and nutrients that it’s often called liquid gold.
Colostrum also has a gentle laxative effect, helping your baby pass their first bowel movements—called meconium—a sticky, tar-like substance that’s been building up for months. (Robin Williams once joked that meconium was like a cross between Velcro and toxic waste!)
At 36 weeks pregnant, you’re about 9 months along.
Not quite. Full term is considered 39 to 41 weeks. Babies born between 36 and 38 weeks are classed as early term.
As your due date nears, you may be on high alert for signs of labour. Of course, contractions, waters breaking, and cervical changes are the “big” signs—but there are also less obvious ones. For example, some people experience a sudden bout of diarrhoea in the days before labour. It’s your body’s way of “clearing out” before birth—not glamorous, but practical!
The start of labour is still something of a mystery, but hormones are definitely in charge. Your baby actually plays a role by releasing CRH (corticotropin-releasing hormone), which signals the placenta to produce more oestrogen and cortisol. These hormones cue your uterus to release oxytocin, the key hormone that kicks off contractions. Prostaglandins also soften the cervix, preparing it to thin and open.
Some people describe early labour pain as period-like cramps or a dull ache in the lower back (a hot water bottle can help). This early stage may be slow to build or progress quickly. If fast labours run in your family—or you’ve had speedy births before—give your midwife or doctor a heads up!
At 36 weeks, you may notice:

It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
