don't see any reason to wait even 2 weeks, in general babies are more at
risk from over heating than getting too cold, obviously you don't want them
to get hypothermia, but that is caused by prolonged exposure to cold, rather
than a hour outside, the baby will let you know if they don't like it!

thanks for the advice. I know being in the house I'll go stir crazy
and October weather is very pretty. All the smells for fall are
awesome.

Is it true that if babies get too cold they'll cry and fuss?
