Naturalised parent, child awaiting status

[somy29]

Hi all, I've been naturalised on 27/8/13. I applied for my 5 yrs old daughter for naturalisation on early September 13. She was born here in Ireland in June 2006. I was only 2 and half years in Ireland when she was born. I received an acknowledgment letter re: her application by mid of this month. My query is:

- her stamp visa ends on early October, how can I renew her residency?? And what documents I will need to do so ????

- how long usually it takes for a child of a naturalised person, to get their application approved????

I really appreciate your help and guidance
