Pls advice needed for extension flr(O)

[Muffin007]

Hello
pls i need your advice..
i want to make sure i have the right things before hand.

I got DLR in oct 2013 based on the parent of a british child. The father and I don't really talk so I'm solely responsible for her..Its going to expire in April 2016..please help me with the ffg questions:

1.How soon can I apply (really worried with the new govt)?

2. What would they need for extension? any proof from the dad to show hes supporting? what if he doesnt support at all?

I'm not claiming any type of benefits at all and i pay for her nursery,house rent from my hard earned work..I have my own company which i'm contracting from and I'm director?

Will they want to also see any form of employment or company records?

Thank you in advance

N.B MY 10 year in UK will be DEc 2016
