155/366 - Christening or Baptism?

It was madam's Baptism today. We have been having some debate on what is classed as a Christening and what is classed as a Baptism. It is definitely the latter in madams case as she is 4 and I "think" that Christening refers the babies. Although I could be completely wrong. It is rather confusing. Anyway a very quick photo for this evenings as I have been ploughing through photos and lost inspiration tonight.
