Evening lovely Milky Mob, I am not sure why I didn't think to share this personal hack sooner, my apologies. As a former baker/cake decorator, I have a plethora of kitchen gadgets, especially many that measure. When it comes to measuring milk, I have employed many that are mini as I have yet to eclipse as ounce 🤦🏼‍♀️. I have found that my 5 ounce Anchor Hocking measuring glass has been particularly handy when expressing, and thought some folks who are producing in the lower numbers like me, may also enjoy it. Please ⚠️ use caution as this is glass! Otherwise, it is so handy as it measures in tablespoons (Tbsp), milliliters (mL), ounces (oz), teaspoons (tsp), and even has some ¼ and ½ cup markers. Just thought it might be helpful for some folks.
