Don't use the squadron putty if you are worried about the fumes in the vicinity of someone who is pregnant, it contains Toluene. The label on the squadron putty says: "Toluene may produce birth defects in the developing fetus"
I don't have a good alternative to offer. Milliput can be thinned out with water and a sculpting tool and sometime I use gap filling super glue. I too have been looking for a non-hazardous replacement filler.
Don't worry, unless you happen to live in the state of California, just look at the warning in the tube!
Well, let's get serious again. I wouldn't worry about toluene in putty. The amounts used in modeling are quite small, and if you take care of proper ventilation, you should have nothing to worry about.
Although I still wouldn't recommend pregnant people deliberately sniffing squadron putty... I think having a hobby room or avoiding building in the vicinity of the pregnant person plus having at least a window near your workbench to provide ventilation should be enough.
Still, I can't look at the warnings in the tube without thinking about those American McDonanld's coffee cups that have a "contents may be hot" warnings... Perhaps some company got sued because of the absence of elaborate warnings in the container, of Calofornia just has strickter chemical laws.
I prefer Squadron green putty myself. The texture is a little coarser than in the white kind, but it the carrier fluid doesn't have the habit of separating from the rest of the stuff. (happened to me with the white putty just once, but it reminded me of the Revell putty. Usually just clear liquid came out of the tube...)
After green putty and a bit of sanding, I take care of the rest of the irregularities with mr. surfacer if needed.
Super glue hardened with kicker is something I like to use too, with minor seams and smaller areas.
