I have not been following the whole conversation about six month old not
interested in solids, so forgive me if this has already been said. My now
eight year old did not take solids till he was about 8 months old. It was
a
combination of his not being interested and our being in a difficult state
of transition (overseas move, death in the close fammily) and nursing him
was just a lot easier. Once he took solids he was fine.
Hope this is helpful.
