Weird Habit?

Does any mummy has the weird habit of smelling your bolster while sleeping?

I have actually stopped after I went to high school but I discover that the smell (er, not to sound too yucky but is your own unique smell la) seems to helps to soothe my nausea feeling in my 1st trimester and currently the Braxton Hicks contractions which I have been experiencing more lately. To put it simply, it's like your "smelly pillow" (臭臭)  one might have during the childhood days.

I hope I am not the only weird mummy. =}
