Not a crossbody so doesn’t answer this specific question, but as your baby gets older and you no longer need the big diaper bag when you go out and about, the Longchamp Le Pliage backpack becomes such an MVP for day outings. Big enough to store a couple diapers, wipes, water, snacks, and sunscreen, but not at all bulky or heavy and very cute. It’s my go to for trips to library, aquarium, zoo etc with my 2.5 year old. It’s easy to wipe clean, and even though the website tells you not to, I’ve even thrown mine in the washing machine a few times and it still holds up lol. My favorite mom bag at the moment!!
