My 2 have weetbixs with fruit or sultanas, cornflakes or rice bubbles, sometimes they will have whatever "grown up" cereal we have in. Eggs. scrambled or boiled are a favourite here, beans, cheese on toast, piklets (you could make them the day before), porridge with a splash of maple syrup, fruit and yoghurt is another big hit- I just use tinned fruit when I am in a hurry.
