There’s nothing like the smell of a baby. The sweet scent of the top of your baby’s head is intoxicating like nothing else.

Scientists estimate there are about 150 chemicals present in baby body odor, and while they haven’t yet pinpointed exactly which one makes it smell so good to mamas, we do know that none of them can come through the phone.

That’s bad news for Hilary Duff, because this mama knows that when you’re far from your baby, you miss that smell.

“Ever try to sniff your baby through the phone?” she joked in a recent Instagram post.

Duff’s hashtags indicate that she was feeling “desperate” to sniff baby daughter Banks, and while she was joking, it’s also probably not far from the truth.

The science shows the scent of a baby has calming properties, so it makes sense that mamas might feel a bit addicted to that smell. Seriously, studies suggest that the scent of a baby’s head impacts our brains similarly to drugs used to treat mental illness

Researchers in the Department of Clinical Neuroscience at Karolinska Institutet in Stockholm had 30 women smell little hats previously worn by newborn babies. As the women inhaled the scent the researchers studies their brains with a magnetic camera, according to Sciencenordic reports. The images showed the smell was impacting the brain similarly to certain drugs.

Scientists are onto this baby smell thing, and are trying to figure out a way that the power of baby body odor could be used to treat depression.

It would be awesome if they could also figure out a way to transmit it through the phone. (Hey Apple, we’ve got an app idea for you!)
