I'm not sure I believe in gripe water. It contains sodium bicarbonate so if there's a touch of reflux or indigestion it will instantly neutralise the stomach acid but (and here's the science bit...)
HCl (in stomach acid) + NaHCO3 (in gripe water) -> NaCl + H20 + CO2
Therefore gripe water produces gas because it reacts to make carbon dioxide! So after it she might burp but it's just the gas from the reaction. Also it produces salt in the stomach which when you're on solids isn't great because it's hard enough as it is to keep to below the recommended 1g salt a day.
So... The usual culprits blamed are cruciferous vegetables, ie broccoli, cabbage, cauliflower etc. Do they cause wind? Personally I never find they do with me. I find garlic is more of a culprit! I do think though that whatever you feed there will be a bit of digestive system adaptation time. I'm not sure what you can do about that, maybe just try things and see how she is? I think it's very easy to see a reaction and think *it's definitely that which caused it* but you can end up really restricting your child's diet if you're not careful. I remember seeing my son's eczema flare up slightly after some egg and I avoided egg for a few weeks till I mentioned it to my health visitor and she recommended trying it again and there was no reaction at all.
Good luck. I remember 6 months being a fussy time but things get better soon.
