Absolutely. You should have heard the outcry from my elder two boys when we told them they were getting another baby brother. My 6yo still brings it up that he is sad I am the only girl in our family. Its taken a long time for him to even talk about the baby in gender specific terms I feel really horrible but I try to validate his feelings while explaining that once the baby is here he truly will not care. It can be difficult for them to understand that gender of baby isnt a choice and that sometimes people get all one gender of sibling. My eldest often asks why everyone else (and Im sure it feels that way!) gets brothers AND sisters but he only gets brothers; and 3 at that!
