AIBU to think that all the criticism of his parents for keeping the christening private is very misplaced. This is deeply personal and why shouldn't they keep it among close family and friends? They will be publishing some photos afterwards.
Many pundits in the press are linking this to the recently released figure of £2.4m to do up their house at taxpayers' expense, but I do not see that they are linked. Who should pay for the house (I believe they should) is a different issue. It should not be a trade off - cost of house in exchange for seeing baby baptised.
