Visit Visa for Parents and Statment

Hi,

I am applying for visit visa for Mother and Sister, My Dad is submitting 6 months statement and showing that he will cover all cost (travel/other's). I am also sending supporting documents (6 month payslips, full time employer letter, Flat Tenancy Letter/Council Letter Bills).
Question: I have only one month bank statement which has balance of almost 3000£. Is that enough statement in addition to supporting dad bank statement. Or Should i not need to submit any statement.

Regards,

Any comments on below:
