Your pregnancy: month 7

Your baby is starting to look and act like a newborn – he’s sucking his thumb, rolling and kicking those legs, and hiccuping like a pro!

Weeks 26 and 27

Your baby is the size of an: eggplant

Your baby’s hearing is so well-developed that he reacts to sounds and its pulse increases. His eyes are also opening and starting to see! Your baby is beginning to develop patterns – of brain waves, sleeping and waking – which are preparing him for life in the outside world. You should be feeling a lot of movement now.

By week 27, your baby measures nearly 14 inches and weighs just over two pounds. He might start to recognize your voice at this stage. If you feel rhythmic spasms in your belly, don’t worry – your baby probably has the hiccups! Some babies start sucking their thumbs at this stage to soothe themselves.

Weeks 28 and 29

Your baby is the size of a: cauliflower

You’ve reached the third trimester – congratulations, you’re in the home stretch! Your baby is getting ready for life outside the womb by developing more brain tissue, growing more hair, storing more fat, dreaming, blinking and breathing. You might notice your symptoms are changing again, with leg cramps, swelling, insomnia and constipation now plaguing you.

At 29 weeks, your baby has almost reached full length but still needs to add energy-producing white fat to his frame. The brain, muscles and lungs are continuing to mature. Now is a good time to start performing daily kick counts. Lie down (preferably) and count all your baby’s movements over the course of an hour. If you don’t feel at least 10 in that time, have a snack and try again. If it takes two hours or more to count 10 movements, consult your doctor.

Week 30

Your baby is the size of a: small cabbage

Your baby now weighs three pounds. With all that extra fat, your little cabbage is starting to control his own body temperature and the fuzzy lanugo is beginning to fall off. The hair on his head is getting thicker and the fingernails are growing. And the body and head are finally in proportion – your baby is really starting to look like a newborn!

Tips of the month: If you’ve put on more or less than the healthy range of 16 to 22 pounds by 26 weeks, talk to your doctor about what you should do to get back on track. Now’s a good time to sign up for a birthing class – it will help you prepare for the big day. Once you hit the third trimester, make sure you eat plenty of iron-rich foods (red meat, chicken and spinach) because your baby’s iron requirements are higher.
