In a blender, combine milk, chia seeds, hemp seeds, and flax seeds, and let them sit for about 10 minutes to activate chia seeds.
To the blender, add frozen banana, peanut butter, and Nesquik Chocolate powder. Blend on medium speed until the banana is fully dissolved and the shake is thick.
Serve immediately.
Notes
the recipe has peanut butter in it. Make sure there are no known nut allergies in the team should you decide to create these shakes for everyone. When in doubt, use a nut-free alternative like sunflower seed butter and let other parents know the ingredients in the shake.
