How about if you did the dressing and hair thing first then the breaky part? Maybe she will eat better if she's not so rushed and maybe you won't need to rush her if she's dressed first?
Or can you take something to kindy for her to eat there, like a breaky bar, fruit or a boiled egg? Maybe pack a lunch box of non perishable foods for her to eat at kindy if you think she doesn't get enough to eat during the day, she may be more likely to eat it if it's 'hers'. She could help choose from a certain selection you have approved the night before.
