Do we have to?

So do I have to be a first time mom in order for me to be over the moon over the fact that I'm pregnant with my second? Some girl said that females shouldn't be be praising their other pregnancies besides the first without acknowledging their first kid? All because of numerous post about the baby on the way. Is she right or wrong? I feel like she's wrong, you should be able to be excited, & post as many things as you want to about your new baby that's on the way especially if you've been trying for so long, ya know? What are you guys opinions?
