Add the milk, honey, and Greek yogurt to a blender. Blend on high speed until you have a smooth mixture and everything is fully combined. Move the mixture to a medium bowl and add in the chia seeds. Mix until combined. Cover the mixture and put in the refrigerator for four hours or leave overnight.
Add the raspberries to a medium bowl and mash lightly.
In 6 bowls or glasses evenly distribute the mashed raspberries.
When the pudding has set for at least 4 hours spoon it over the top of the mashed raspberries.
Top the bowls or glasses with a handful of blueberries and serve.
