First of all I would like to stress that I don't mean to upset anyone! This is just something I've been wondering about. Every baby/child I know here in England who is bottle-fed has had one or several bouts of gastro-enteritis, some so badly that they had to go into hospital. In Germany, where I come from, they say that you should never make bottles in advance, but always make them fresh. I don't know that many babies there, so I can't comment on the gastro-enteritis, but I seem to have heard about it a lot less. So, what's your experience?
