Yes, I think it has something to do with all of the hormones and pheromones your body is releasing. My dad craves white castles just like I do.
My mom and step-dad have my symptoms, a lot of people in my family start having the symptoms when they're around me a lot. (My baby's father isn't in the picture, because of him being abusive.) I think anyone that loves you and the baby can get the symptoms.
My mom gets sick all the time and gets my cravings. And so does my baby's father.
My husband had weird cravings shrimp and ice cream...
His mom said she felt the nausea also so I guess other people can feel it also or it could just be a coincidence. Who knows but they were right.
My hubby had nausea & vomiting before I found out I was pregnant his mom was the one that brought up the idea that i was pregnant.
I ended up two days late took a pregnancy test and yup I was pregnant :)
