Have just been trying to finish off before the arrival of little one. Sanded down a few areas of newly plastered wall on and off for a couple of hours and wondered what impact I might be having to me or baby. Any harm caused? Did try a mask but couldn't breathe! and also steamed up glasses protecting eyes. Windows were open but expectedly there was a lot of dust. Can't wrap myself in cotton wool, jobs need doing, however want to keep well for both of us, bit late now as all done but am a bit worried
