Third child baby shower

Emma • 💖10/12 💙06/15 👶 04/18

We have a daughter who's almost 5, a son whos 2 and we aren't really planning this baby yet so we had gotten rid of a majority of his things.. well we're now pregnant with baby #3 (6w 5d). My mother in law is already thinking baby shower but I wasn't sure if I really should since it's our third. I'd love to celebrate our newest baby with family and friends. Would it be tacky to have another? I wouldn't register for anything big just maybe clothes, towels, baby toys etc.
