The old wives' tale is the more nauseated you are, the more hair your baby will have.
Somehow, that actually tends to be true. Not always. But maybe the same hormones that make you nauseated grow hair. I don't know. ;D
That's an old wise tale. I had heartburn all the time with my first baby and he barely had any hair.
People say the but my sister in law had tons of heartburn but her baby came out with no hair lol
