Congratulations! You have such an exciting time ahead.
For me personally, the tiredness of pregnancy, especially late pregnancy, was unquenchable. I was exhausted and slept all the time. But the tiredness of a lack of sleep feels different and more manageable.
My second pregnancy, I was knackered, looking after a 3 year old. But once he was born, even with a lack of sleep, I felt amazing, because that pregnancy exhaustion had lifted.
This is just my experience, nap whenever you can, rest, put your feet up - literally.
Exciting times ahead, the births of all 3 of my kids was amazing, but my firstborn was incredible, soak up every minute of it. I think not knowing the gender and guessing wrong was just lovely too. I've had two where I didn't know and one where I did and I'd always say to a mum to be, when asked, don't find out before hand, it made my births much more exciting. Yes, it's scary, tiring, life changing - but it's also absolutely wonderful. Sorry, I've just gone off down memory lane 😂
