Going on maternity leave is a significant pregnancy milestone. As you leave your working role, the reality of beginning your role as a mother may hit you-but you hopefully have a few more weeks to get used to the idea!

It can be a welcome respite to take it easy and not have to rush around in the mornings, and you'll feel less tired by not having to travel to work. Although you need to take it easy, it's a good idea to plan some outings, since not having a routine can take some getting used to. Although it's good to stay in touch with colleagues, try not to fall into the trap of logging on to work emails or staying up-to-date with what's happening at work. You might be worrying about losing some of your identity while you're on maternity leave; this is a common feeling but you'll find that before you know it your leave is over and you're settled back into work again.

Try to enjoy this lead-up to the birth and make the most of the time (see Making the most of maternity leave) to get organized and prepare for your new arrival.

Engagement is when your baby's head starts to move down into the pelvic brim in preparation for birth, and this can occur any time in these final few weeks of pregnancy, until the start of your labor. In the last weeks of pregnancy, your doctor will check to see if the head has started to engage, or drop, sometimes called "lightening."

Your doctor will do an examination to check to see where the baby's head is. This is called the station, and it's measured from -5 (the baby's head is floating above the pelvis) to +5, the head is at the opening of the vagina. This last stage is called crowning.

When your baby drops, you may find it easier to breathe, since your lungs will have more room to expand, or the need to urinate more because of more pressure on your bladder.
