Hilary Duff — who is expecting baby number two — recently admitted she was 'so nervous' her second child would be a baby boy (she's already mama to a six-year-old son, Luca). You can probably guess what happened next (hint: The actress found herself under fire via Internet comments for having a gender preference).

Hilary was thrilled to learn her second child would be a girl, but not all of us have that experience. More recently, Khloé Kardashian admitted she had wished for a baby boy — but that upon meeting her daughter, True, she realized she couldn't imagine anything more perfect. Again, the new mom found herself fielding criticism after admitting she had a preference.

Some pregnant women feel a deep gut instinct that their babies are one sex, only to be thrown for a complete loop when they hear that hunch was wrong. Some desperately want to experience parenting both boys and girls...but seem to conceive the same sex over and over. And some women dream of recreating the relationships they had with their own moms (or, on the flipside, experiencing that sweet mother/son bond), but are disappointed to learn that won't be happening.

Ultimately, any baby is an absolute gift, and of course we want our babies to be healthy above all else — but that doesn't mean it's wrong or abnormal to want something more specific and to be upset when you're denied it. And while it may seem trivial to someone who is struggling to conceive, has experienced miscarriage, or has an unwell child, there's no need for us to shame moms who wish for one gender over another — or moms who are disappointed when that wish doesn't come true. If you're going through gender disappointment now, here's what you need to know.

It happens to the best of us

According to Dr. Vara Saripalli, a Chicago-based psychologist who specializes in pregnancy, prenatal and postpartum care, expectant parents who experience gender disappointment are not alone...though it may seem that way from time to time.

What it really comes down to is this: There's nothing wrong with being a little let down when you open that gender reveal box and see blue again or feeling your heart sink a bit when you hear 'it's a girl!'. Whether your reason has to do with family balancing (you were really hoping for a son after four daughters!), something as simple as not being able to give your baby the name you chose, or another reason entirely, gender disappointment is natural. It doesn't mean you love your baby any less, and it certainly doesn't make you a bad mom.

The expert's advice

Dr. Saripalli's advice for women who are dealing with gender disappointment? 'The most important thing to remember is that there is no such thing as a bad feeling, and it is okay to feel how you feel,' she said. 'Sometimes disappointment stems from fear that you won't know what you're doing. It can be helpful to work through those concerns, do research, or talk to friends who have children of your baby's gender.'

There's no need for shame

So let's stop shaming moms who are open about wanting one sex over another. Let's understand that it doesn't mean they're not grateful for what they've been given. And let's show ourselves some more kindness too!

Gender disappointment happens. It's real, it's understandable, and it's nothing to be ashamed of — and if you're experiencing it now, know this: You're going to love that baby like nothing else. And you're going to be an amazing mom.
