Probiotics during pregnancy to help baby not develop eczema

[PigsWiggle]

I've read that some studies have shown that taking probiotics when pregnant may help the baby not to develop eczema. But I can not find any details about if you should take probiotics throughout pregnancy or just first few weeks or only last few weeks. Or if you should continue taking probiotics when breast feeding.
It would be great to hear from anyone who knows anymore about this, thanks.
