I have it a strong sense of smell too. I could smell if my dh had a beer a few hours after he went out with the lads! So it can be useful at times. Other times, I wish I could switch it off. Yes, I am also very sensitive to molds, pollens, and other environmental allergens.

My family has the strong senses of smells and tastes. My mother and I cannot wear perfumes and are very sensitive to certain fragrances, shampoos, laundry detergent and softeners, etc. Some of my family are on the autism spectrum so some of it comes with the territory of being on the spectrum, having SPD, and being gifted.

My 2e pg ds 7.5 was born with severe SPD. Oy. We had all kinds of fun and games with him with smells, tastes, visuals, sounds, touch, textures, vestibular, etc. And we were living in NYC. I remember when I was pregnant with him, I couldn't walk past the olives, cheese, and coffee bean area in one particular shop because he would pummel me inside.
