Daddy's headaches!

Jess
Hey guys! 
I'm now 26 weeks pregnant and since I've always had terrible migraines since I was a child I've had a lot of struggles with that during my pregnancy, however my husband never but really never had a headache until a week ago approximately. He's getting headaches everyday! My MIL says that's because of the baby and the sympathy symptoms. Are any daddy's out there experiencing the same?
