Gender disappointment

I’m not sure if this is the right group, if not I do apologize.

I have a friend who has been trying to conceive their 2nd child for 2 years now. She has had 2 miscarriages which includes one ectopic pregnancy which resulted in one of her tubes being removed.

By the absolute grace of God she fell pregnant. She is now 18 weeks and just found out that she is having another boy and she spends the whole day crying coz she wanted a girl.

I find this extremely ungrateful anybody in her position would be over the moon to be expecting a healthy baby.

Am I wrong here? Should I just let her be and not say anything? Should I be more respectful of her feelings?
