Dealing with comments

So we have beautiful 3 year old girl and due our second any time soon.. We’ve not found out what we’re having, just like we didn’t the first time around.. Theres been a few indirect comments about having a boy from certain people… My question is how would/have you navigated this? I feel like it’s those that are fresh or older but that’s no excuse and it’s just plain rude. Of course it’d be nice to have a mixed family but if this is a girl we’ll still feel so blessed and so incredibly happy. I just dont want any negativity
