Has anyone given their LO oat milk? I’ve done a lot of research and it seems to be closest to whole milk calorie wise. We need to switch to something dairy as soon as possible and i’m trying to find the right option. I give her pediasure and whole milk now and it’s not working great for her. causing a lot of mucus so I need something higher in calories and fat. Only has 5 grams of fat per serving but i’m finding that all the other options have much less and much less calories.
