I know that nothing I say is likely to make any difference because you're having your first baby and late pregnancy is uncomfortable and you just want it to happen now.
But here goes.
When your baby is born, which might be today or in a month's time, your life is going to change beyond recognition. It may be months before you sleep for more than three hours at a time. You may have perineal stitches or a C-section wound or postpartum piles to deal with. You may be breastfeeding and finding it difficult and painful. It may be a very long time before you feel you can go to a restaurant, or go to the pub with your friends, or just leave the house without planning it all like a military operation. (Alternatively, it might not be like this. You might have a straightforward labour and recovery, and breastfeed easily or formula feed, you might have a baby who sleeps through the night from 6 weeks and is basically a dream baby in all other respects. You might have a glorious summer catching the rays in pub gardens while your little one naps happily in the pram.)
My maternity leaves were basically a mix of the above and were wonderful and exhausting and overwhelming at the same time. Overall I loved them and wish I could do it all again.
But if I could do it all again, and in particular if I could do it all again without having two small children to look after, I would spend the end of my maternity leave not trying to get the baby out, but spending every day enjoying as much "me time" as possible, meeting friends for lunch, going swimming, taking naps, reading books, baking cakes, basically squeezing out every last drop of baby free time. I was a bit better at doing this kind of stuff the second time round, and as luck would have it my husband was between jobs and my older child was at nursery during the day. I still have fond memories of the day I hit 40 weeks, when we got the train into town for a growth scan, then walked across town to a really nice restaurant where we had a leisurely lunch, walked some more to browse in the shops, then went to a separate medical appointment in the afternoon, and then hung out with our toddler after nursery and watched a film together in the evening. It was such a lovely day, and then two days later I was holding my gorgeous girl and our lives had completely changed again.
Change comes soon enough, and unless you are going through something really terrible, try not to wish the time away.
Good luck to you when the time comes!
