Two days ago, I decided to show my pregnant belly to my toddler to "introduce" him to the new baby. I lifted up my shirt to just reveal my tummy and I said "Look! Baby is in here." He quickly put my shirt down and walked away. I didn't think anything of it. The very next day, he had his first 100+ degrees fever ever. It only lasted 24 hours. This morning, he was SUPER clingy to me and he's usually like that with dad. My DH was sad about it (like he was losing his son or something) so I kind of just ducked out of the living room where we were at and let them hang out together to reconnect. And just an hour ago, he threw the most massive tantrum in the middle of his nap. And the whole time he was bawling "Ahhhh mama...ahhhhh mama" and he never cries for me like that. And he hardly ever wakes up in the middle of a nap.

I'm wondering if his change in behavior has anything to do with my pregnant. Or if I'm just thinking this all up in my head.

Do you think a toddler can sense when mommy is pregnant?
