Nursery theme?

I need help deciding what I'm doing in the nursery. I was totally sold on having an adorable vintagy Beatrix Potter theme but, of course, it's a little harder to find Beatrix Potter anything these days without spending an arm and a leg. My other idea is going simple with elephants because I LOVE them so so much but I don't want grey or white walls so it would have to look ok with the cream walls. Elephants are also way easier to find budget wise but I'm just not sure if I'm ready to let go on my original idea. I have no idea why this is the pregnancy dilemma I got stuck on but PLEASE SOMEONE HELP ME 😂

If it helps the decision we have all the furniture and it's a dark natural wood (not 100% the kind as they were hand-me-downs) and the carpet is a neutral grey/beige colour and white curtains. We don't know babies gender.
