Background- DD is 6 days old and is ff on Aptamil. I had planned to bf but have now definitely changed my mind, and she's now on Aptamil ready made bottles and cartons. Because I hadn't planned to ff I'm not very well up on all the information, but soon we'll be looking to make up feeds from scratch.
So I get that the water has to be boiled, cooled to 70 degrees celcius then the feed can be mixed. DH bought a warmer that heats bottles quickly, and I thought we'd be able to use this to heat/cool boiled water to exactly 70 degrees for mixing the food. I thought this would mean we wouldn't have to mix everything up half an hour in advance, but could just boil it, then cool and mix straight away, then feed. DD isn't that regular in her feeding yet so we don't necessarily know when she's half an hour away from wanting a bottle. However, the device DH bought only heats up to 30 degrees celcius so it won't be enough. Is there a product we can buy that heats/cools to 70 degrees celcius? Or what do other people do- surely everyone else doesn't know exactly when their baby will be hungry with half an hour's warning? I know we can't mix the feeds up in advance. Would be grateful for any advice- the cartons are pretty expensive. Unless DD starts crapping money, of course.
