we are having a ****ie issue atm, kids think it has nothing to do with the fact that they scraps of food lying around lol anyway, my son uses it on a regular basis, and i try not to be in the same room, but it happens, im only 21 weeks, and have probably inhaled a few fumes, we have the woolies brand one too. I guess as long as its not inhaled on a daily basis then it should be ok.
