Baby Shower Congratulation Wordings Friend Announced She's Having A Baby! Do I Give A Gift Now, Later At A Shower, And When The Baby Is Born?

Friend announced she's having a baby! Do I give a gift now, later at a shower, and when the baby is born? - baby shower congratulation wordings

This is the first time one of my friends has a baby, I'm not sure that the right way to make donations. Is it some type of decency to announce a gift now, if the parents expect? Or should I wait until the baby shower? And if they are now something that would be good to give a "wait Congratulations" gift?
