  • How big is your baby?

    By the end of the week, your baby will be 35cm from crown to rump, or 47cm from top to toe. She’ll weigh in at almost 3kg and be the size of a honeydew melon!

  • How is your baby growing?

    There’s very little space in there now for her to swan about, so she won’t be doing the big kicks and bumps you experienced earlier on – she’ll just be wriggling about trying to stretch those limbs.

    Her immune system is still developing so it can protect her after birth. Some antibodies she’ll get from the placenta.

    Your baby’s sucking is established, and any part of her body that comes close, she might latch onto and suck away. Most of the languo – the fine, downy hair that covered her body – has gone.

    The hair on her head, however, could be getting thicker. Head hair varies between each baby – it could be just a few strands or a thick crop that’s a couple of centimeters long.

  • What’s happening to your body?

    You’ll see your midwife for check-ups each week now. One of the checks she’ll do is looking for effacement and dilation of your cervix. Your cervix has to change a great deal, or ripen, so your baby can move through the birth canal. Your cervix becomes softer and thins and then begins to open, or dilate.

    When your cervix starts to dilate, the plug of mucus that has sealed your uterus can become loose and fall out. This is what happens when you have a ‘show’. You need to have a fully effaced and dilated cervix before you can give birth vaginally. This can take weeks or happen almost overnight.

    So if you’re told that you’re effacing and dilating it doesn’t automatically mean you’re about to go into labour, and if your cervix isn’t ripe, it doesn’t necessarily mean you’re weeks away from giving birth either. Make sure you have your hospital bag packed, just in case! Also, make sure you go over your birth plan with your midwife and birth partner, so you know everyone’s clear about what you want.
