I am the American mom, and if we move to London in 2months, we won't have the time to go through the NHS waitlist for an eval and a dx for a 2.5 delayed ds (i was thinking speech only but it is now clear it is also cognitive). So we'll have to dx privately and I am wondering if someone can recommend a developmental ped who has a good reputation in London. I called the Portland Hospital and was given the name of Denise Challis, but Googling her did not produce anything of substance.
