What follow-on formula for suspected CMPD?

Hi, just a quick question: my daughter is now 5 and a half months old, so I’m planning to switch her to stage 2 formula. But I don’t know which one to choose. My daughter had a reaction to regular Nan Pro, then we tried Nan HA and AR because the eczema persisted (not better, actually worse). We ended up on Nutricia Soya, along with special soaps and creams, and now the eczema is under control (could be due to the soya, or it could be due to the creams). She doesn’t have reflux, but she spits up if the formula is too watery, which is why we went with Nutricia. At 3 months, blood was taken to check for cow’s milk allergy, but nothing came up from the blood test. So that’s why I’m asking: which follow-on formula would be best? Just soya 2, or try a regular follow-on from Nan or Nutricia? I think it’s silly to give her soya if she doesn’t need it, because I’d also like to give her those light-colored yogurts from Gervais/Danone from 6 months onwards.

Thanks in advance!
