(Since this board is a bit slow!)
How old were you/DH/SO/your kid(s) at baptism?
I was 5 months old (and as a kid, I couldn't believe my parents waited so LONG to baptize me! ).
DD1 was about 2.5 months old (and the youngest one baptized at that Mass, out of 6 babies).
DD2 will be 5 weeks old, due to schedule conflicts with the rest of the available dates!
(No idea on DH.)
