Baby Gift Thank You Cards What Is A Reasonable Wait Time To Receive A Thank You Card From A Friend For A Baby Shower Gift?

What is a reasonable wait time to receive a thank you card from a friend for a baby shower gift? - baby gift thank you cards

Two months ago I had a friend a baby gift because he could not attend the shower. They almost never talk to his friend, but I wonder whether he has received. Is it rude to ask whether or not? Reported a thank you card that they received, but nothing happened in the mail. What should I do?
