Maybe change blends that you smoke before being around the kids ? Recently, I was actually complimented by a lady family member about 'the really nice smell' of the tobacco I was smoking. This has happened to me quite a few times. If you're like many men, the smell of your pipe may be something your children fondly remember about you in the future.
On the other hand, the smell of a cigar on my clothing often gets a negative reaction from non-smokers.
Incoming . . . stoggies !
