Microwaving formula in the bottle?

[DillyDallyDayDream]

Yes or no?

Microwaved food continues to cook after it's been in the microwave. Ever melted chocolate in the microwave? You only need to put it in for 10 seconds, when you take it out, it's still in blocks, not melted at all. Wait a minute or so, the chocolate melts.

I'd never do it. Plus, don't really see why babies need warm milk anyway.

Visualise - think about breast fed babies who have expressed milk. When feeding from mum they get warm milk so when in a bottle you tend to make it warm to represent the same thing

I dont think babies 'need' warm milk, in the same way i dont really need to drink cosy blackcurrant juice. But i do because it goes down nicer :)

Microwaves cook food in two ways, one being the microwaves heating the food and the other being conduction of heat from hot bits of food to cold bits. Once the microwave is off no more heat (energy) can be added to the food, it just gets redistributed by conduction. For solid food you need to leave it to stand to get the conduction to redistribute the heat evenly through the food and eliminate hot spots. For liquids, such as milk, stirring or shaking distributes the heat evenly more quickly.

In your example Visualise, when the chocolate comes out of the microwave, some of the chocolate is very hot, well above melting temperature and some is below melting temperature. Leaving it or stirring it makes the very hot chocolate a bit colder (but still above melting temperature) and the colder chocolate a bit warmer, so that it melts as heat is transferred from the hotter chocolate to the colder chocolate.

Just shake it! Hot spots gone, even temperature.

I shake mine too!
