“Apushatayid- you’re right I should have rephrased the question- “Did anyone hear of ashkanazim making a simchat bat”? Happy??”
Yes. I have heard of ashkenazim making a simchat bat. some people call it a “kiddush in shul on shabbos”, while others do something during the week when the family can be together. there are many ways to thank hashem for the bracha of a daughter.
