Hi Sam,

I hate to say it, but given the known effects of lead on the brain of 
children,  I'd be hesitant to let any small child anywhere near a 
soldering environment.  I'm not sure that there should be any lead fumes 
at soldering temperatures (although I see some websites report lead 
oxide in fumes), don't forget the tiny solder balls that form while 
soldering.  Also, many components have 'tinned' leads. The "tinning" 
being solder.  I'd be careful to make sure there's no way your son could 
be handling anything with lead on them, and then putting his hands in 
his mouth (or some other more indirect ingestion method).  It also 
reported that rosin fumes cause asthma.

All in all, electronic components, soldering, etc isn't the best thing 
for a small child to be around.
