How to Heat Baby Milk/formula in the Microwave.
Intro: How to Heat Baby Milk/formula in the Microwave.
Everybody knows you're not supposed to heat breast milk or formula in the microwave. Why not? The top two reasons usually cited are 1) it kills nutrients, which is scientifically unfounded, unless you're leaving it in there for 20 minutes, or 2) it creates hot spots, which can scald baby, which would be slightly plausible if we weren't talking about a liquid, which is going to have convection currents and is going to be thoroughly mixed long before it gets to baby's mouth.
No, the only real reason not to heat milk in the microwave is also the best one: because if you do, your baby's momma will kill you. She read all those reports on the internets and she doesn't believe your scientific mumbo-jumbo about upwelling for a minute.
So what's Daddy to do when baby is crying for food and Mommy's out at yoga? Just running hot water from the tap over the bottle takes forever and wastes a lot of water. It takes a while for the water to get hot and then most of the heat is just running down the drain.

STEP 1: Heat Some Water in a Measuring Cup.
Grab the nearest Pyrex measuring cup. Put a couple ounces of tap water into it. Use the hot tap but don't wait for it to actually get hot--junior is hungry and time's a' wastin'! Stick the cup in the microwave for 1-2 minutes. You don't need a lot of water, because the bottle is going to displace a lot. You don't need a lot of time because, well, this is what microwaves are made for!
STEP 2: Insert Bottle.
Stick the bottle in the cup of hot water. Swirl it around. After a few minutes, check the temperature by doing that thing they do on TV and in the movies, which you always wanted to do in real life: squirt some milk on your wrist to see how warm it is.
STEP 3: Enjoy!
Serve warm. Makes 1 serving.

But they make life so easy... I can just flip the switch and boil my energy saving kettle, which boils in less than 40 seconds, and put the bottle in the water to heat.
Making formula is just as easy with a kettle too.
I'd say someone was pulling my leg, but people were agreeing they don't use a kettle.
They're cheap and fast. Whether someone really is pulling my leg or not, (at the risk of looking stupid because you really do own a kettle), if you don't have a kettle I recommend owning one.

Nice to find someone who thinks this way too. So, don't ever forget to discuss this with the lady you want to have children with. :)

Plants get rain water. Rain comes from the sky. The sky is very cold. I know, because I spend allot of time up there. For every one thousand feet of sky, the temperature drops by about two degrees Celsius. Except the first few thousand feet of sky. Those first few thousand feet of sky are much warmer than the rest of the sky, because it is heated by the ground. So after the first few thousand feet of sky, there is a more significant temperature drop. Also, the sky is blue.

Thank you author..! I couldn't find any article with proper scientific backing for why microwave cannot be used on breast milk either..! but apparently, my wife could flash out a pamphlet from the hospital advises against microwave (yes, lost that one, sigh). My thinking: maybe, microwave damages the immune cells found in beast milk (due to heat spots) believed to be helpful to babies. I think there are many factors in breast milk which are not yet understood (which is why formula milk cannot give babies the same benefits as breast milk - we don't know how to replicate artificial breast milk exactly)

For one of the "reasons" not to microwave formula, you cited, "it creates hot spots," and debunked with and argument about convection currents in liquid. While quite true in principle, it doesn't necessarily apply to this case.
Microwaving anything will induce hotspots, just because of the way microwaves are generated and bounce around inside the enclosure.
You are (hopefully!) not heating the formula to very much above body temperature (not more than ~100-105F) or you can scald the baby's mouth. In such a case, the temperature differences between hot and cold regions are less likely to induce good convective flow, and so the hotspots can persist for a substantial time. Also, formula is thicker than water, which reduces the development of convection on short timescales (viscous inertia); you can verify this by heating a bowl of canned cream-style soup in a Pyrex cup.
For both reasons, rather than rely on convection, you really do need to manually mix the heated formula, and check the temperature after mixing. A good approach is to heat in very short steps (5-10 seconds at a time), mixing and checking at each step. This is sufficiently slow and awkward, especially when the young one is getting impaTIENT!!! :-O, that it is really not worth the hassle.
