Katie, my children were fully FF by 4mths and with my first baby the thinking at the time was that solids were started at 4mths, which I dutifully did. My girls were started a fair bit later (5mths and nearly 7mths), but they never had eczema either. Maybe I have just been lucky that my older children haven't had allergies or intolerances, but if I knew then what I know now I would have held off for longer the first time around.

I still think that even FF babies don't need to be started on solids any earlier than their BF counterparts.
