Loveys and Ether

I have always been a little creeped out by the attachment my kids have to their loveys.  Sebastien has taken to sometimes wearing it over his face and he inhales it deeply as if partaking of some illicit drug. 

It turns out, he is self-medicating!  The infant sense of smell is very strong and they draw comfort from the familiar scents trapped in the loveys.  Isabelle. at five, is just imitating her younger brother though for this picture.   I think she now keeps her lovey around more as a psychological crutch (as opposed to an olfactory one).

The thing is, I keep remembering those pictures of ether-users in the 1800's who drew comfort from inhaling ether from a soaked towel placed on their face (or used it to pass out for surgery).

Now, am I right to be creeped out or what?
