Chistening invitation

A question about : Chistening invitation

Long time lurker asking a question.
My daughter has a baby boy that she's getting christened, I mentioned this to a friend of mine in convasation who said to tell her when It is and she'll get the day of work, thing is my daughter is paying for it all, arranging it all, and doing the invitations for the family and her friends.

I Had no idea when I told my friend she was going to say this as she doesn't pay an interest in the baby or my daughter (I just mentioned it in convo) My daughter had a set amount for the christening and gone a little over budget without inviting my friend/s, ( which I certainly hadn't expected her to anyway).
How do I best explain that my daughter is arranging It all, on a budget, without hurting her feelings. Is it normal for people to 'invite themselves'?

Thanks

Best answers:

• Churches are open to the public. A christening is not a private event. If extra people go along, it will not cost your daughter a penny.
  I'm not sure what the issue is, nobody needs an invite and there would be no impact on any budget.
• Just be honest and straight about it, that as far as you know, its by invitation only and your not in control of the invitations. She might be a little disappointed, but she can hardly blame you and will more likely just shrug it off.
• I think OP does mean the celebrations .
• Oh sorry yes I did mean the after celebrations.
• Yes I mentioned the party saying the daughter didn't know if to have it when he should have been born (he was premature) or on his first birthday as a double celebration.
• Some people are just professional gatecrashers.
  I would have said, "Oh no, there's no need for you to go to such trouble, taking the day off work or anything," and then not mention it again, much less when it is.
• I would simply not mention it again. If she asks you then you can simply say "oh, my daughter is organizing everything, I think she is only planning to invite close family"
  Which is true.
  If your colleague attends the same church as your daughter then she will know about the christening as it's likely to be mentioned in other services and the parish magazine, and she will be free to attend the service which , as others have mentioned, is public.
