My boyfriend has been saying this since early in my pregnancy that I smell like a newborn baby and even down there. Today he said my breath smells like baby milk. I googled it and this is actually a thing. Alot of women are trying to find out why their SO tells them they smell like a baby since they have been pregnant. If anyone knows anything about this, please share.
