Both of my pregnancies were pretty straightforward, without any severe morning sickness or unusual symptoms, which I'm super grateful for!
But as you asked about unique experiences, there's one funny incident that comes to mind. So, during my second trimester with my first born, I had an intense craving for durian, the smelly fruit (some might say stinky, but I love it!). I could not get enough of it. It was June, durian season in Singapore, and I would eat them non-stop like there was no tomorrow. My poor husband would shell them for me and endure the smell because he knew how craved they made me feel!
It was a ridiculous amount of durians - three or four almost every day for a few weeks straight. And you know what? My son has loved the stuff ever since he started eating solids. I guess my crazed cravings imprinted on him! He's six now, and durian is still his favourite fruit. He's such a little foodie.
