It kind of depends on her routine. If you don't do bottle and solids at the same time, you're kind of already doing a snack, KWIM? We didn't start snacks until we dropped formula and the bottle at 1 yr, and it made sense for us at that point. If we didn't offer snacks, Tyler would be going 4-6 hrs between meals, and that was waaaay too long for him. There's really no reason to avoid them, as healthy snacks are normal for growing toddlers because their tummies are just too small to go several hours without food. If she's happy and growing, you could easily leave things as they are until she starts showing signs that she needs food more often.
