Seeking Advice as a Mom in an Interfaith Marriage

As-salamu alaykum everyone, I hope you're all in the best state of iman. I wanted to share something that's been weighing on my heart lately and maybe get some thoughts from others who've walked a similar path. I'm a Christian woman married to a wonderful Muslim man alhamdulillah. We've been together for 12 blessed years, navigating an interfaith marriage with lots of love and patience-it hasn't always been easy, but we've made it work with mutual respect. Lately though, we've hit a rough patch regarding our 7-year-old daughter's clothing choices. To give some background: we live in the Middle East where my husband is from, mashallah our kids are growing up trilingual (Arabic, English, French) in an international school. My in-laws are conservative but amazing with our children, masha'Allah they adore them. I've always tried to support my family's faith-during Ramadan I fast with them, our kids attend Islamic weekend school, and alhamdulillah my son completed his first full fast this year while my daughter did half, all by their own choice! I make suhoor for them with joy, seeing how faith comforts them touches my heart. Here's where things get complicated: my daughter dresses modestly by Western standards (and even local ones). The one exception has been knee-length shorts for school playtime in the heat-nothing extreme. My husband has always been about free will in faith matters, never forcing anything. But recently he's become very firm about forbidding shorts for her, despite her being years from puberty. Our daughter has actually said she wants to wear hijab when she's older, completely on her own without prompting! But right now she just wants to play comfortably at school. This sudden intensity has caused stress for all of us. I support my children's Muslim identity completely-we only eat halal, I don't drink or eat pork (though my reasons aren't religious), and I respect Islamic modesty standards. But I'm worried this clothing issue might become a breaking point. Has anyone else navigated similar challenges with daughters in mixed-faith families? I'd appreciate any wisdom or shared experiences. (JUST to be clear-I'm not looking for conversion advice, that's a separate matter. Just some perspective on this specific situation.)
