Nutritionist for kids - recommendations

[CeeCee123]

Hi,
Has anyone used a pediatric nutritionist/dietician? Either one who will do Skype/Phone interviews or someone based in London.
I think my DD has a dairy intolerance and I want to try her on a dairy elimination diet but would rather do it with proper advice/supervision. The GP is not very helpful and I'm not hopeful of getting an NHS referral.

TIA

We had a phone consultation with this lady
brainfoodlondon.com/about/about-jenny-edelstein/ As my son is on gaps diet we needed ideas for breakfast etc. She gave us some fantastic recipes and also talked to his school
She's really good
