I am traveling overseas next month. My journey on Lufthansa requires a plane change in Frankfurt, Germany. My son will be traveling with me and assisting with pushing my wheelchair. Does anyone know whether the airport in Frankfurt has "family-style" bathrooms--i.e., private bathrooms for people with disabilities who are assisted by others?

And are these bathrooms located in both Terminal 1 and Terminal 2?

Are any other European airports (such as London/Heathrow or Amsterdam/Schiphol) better in this regard?

Any other advice/tips not mentioned in these postings that pertain to Lufthansa or the Frankfurt airport would be greatly appreciated. Thanks.
