Questions raised by Cherie Blair’s autobiography

Flicking through an old magazine in the dentist's waiting room I read a quick review of the above-mentioned book which mentioned that "Cherie Blair conceived Leo because she was afraid to take her “contraceptive equipment” to Balmoral".

This raises several questions for me:

• Isn’t she a Catholic?
• What did she worry that the household staff would think of her, that she was a married woman going to bed with her husband and that they may have sex but that she wasn’t planning to have any more children?
• What is the equipment she uses? Is there a Hieronymus Bosch method? Isn’t ‘equipment’ a strange word to use? Especially as no word at all was required, surely ‘contraceptives’ would have done the job.
• Why didn’t they name Leo Balmoral Blair à la Brooklyn Beckham?
