Mornings can be so hard with so much to do. I'm 88, my husband is 94.
I try and do some stuff the night before -
I put the muesli and fruit in 2 bowls with milk and leave them overnight in the fridge. Ok the banana can look a bit off colour and soggy the next day but the milk has a lovely banana flavour, and saves so much time, chopping or peeling fruit.
I put a pile of tissues next to his place at the table ( for some reason his nose always runs at breakfast time) and the little waste bin next to his dining chair for him to throw used tissues in ( or miss the bin, as sometimes happens)
I put his biro next to his place-mat ready for him to 'attempt' the easy crossword in the daily paper
When he's showered and dressed I make him sit on his bed till I've got myself ready and tidied the bathroom etc. Then I stand at the bottom of the stairs and watch him safely down.
We'd have to be saints never to get angry. Sometimes when I've got mad at him I say afterwards - I'm sorry for shouting. He looks puzzled and says he didn't know I had. So he forgets instantly.
We carer's aren't saints, but we are not that far off, so give yourself a pat on the back
