you might ask her doctor.

in any case lead should be a big concern

if you go ahead and the baby has ANY TROUBLE at all mom will blame it
on you and your project

as a note of warning some friends waited till after the baby arrived,
and the job dragged.

their son got into home repairs, by 2 he was helping resand already
finished walls, helping demolish a new section of drywall. you get the
picture. its not good. his efforts made the job much worse.

although it has made for funny stories.....
