Hi Bacpacjac, nice to see your setup.

Its a bit frustrating that so much gear is designed for one or two people, things are a bit different if you need to cater for a whole family !

What works for us is to set out the breakfast into individual servers, including raisins, sugar, sizing (big or small) and any other additives you like, into ziplock bags.
I boil a kettle of water and we put the ziplocks into a cup/bowl to support the bags and so that everyone can hold their breakfast without burning hands etc.

Then we pour the boiled water into each bag and zip it up for a few minutes to “cook” before eating it - from the bag,

Using two stoves (perhaps ever two different types of stoves) means that we have enough water to make breakfast, and can be heating up water for a coffee at the same time.
The kettles and most of the hiking pots we have are too small to make enough water for breakfast and coffees in one go, so its two stoves, or two rounds with one stove.
I like having two stoves, so I have a “spare” (you know the mentality ... lol ).
