Am I being over dramatic?

So my mil has been an angel this whole pregnancy. It’s our first child and my mil first granddaughter. She’s gotten a lot of things for us including a lot of clothes. I was kinda taken aback she got an Easter dress and Christmas dress (both super hideous) already and she’s not even born yet, but I didn’t say anything. I heard my husband on the phone earlier and I heard her say she got another dress for when it’s her second Christmas. Now I’m just fucking annoyed because I feel like it’s my kid and I wanna pick out her damn holiday clothes. Am I being unreasonable or overreacting bc of hormones or no?
