i say dont worry about it, your highlighting the fact that shes doing wrong and punishing her which is great but she is only 5, my daughter is nearly 5 and has good weeks and bad weeks ... sounds to me as tho youu expect to much from her, do you remember being 5 or having a bad day at work and doing or sayin something you regret
also having read some comments such as does she realise its totally unacceptable... imean c'mon she's bein a pain in the arse but i think you maybe bein to harsh.
p.s my daughter isnt a shit and often get compliments on how well behaved she is but sometimes like your daughter she plays up
