Child Visiting visa application from India

Hi All,

I have made MN1 application for my daughter early August. As per all of yours experience, i don't think I will get it in 3 months.
I have planned to travel to India with her next month and coming back within a month. She is holding Indian passport Hence it wont be a problem travel to India but difficult to come back.

Do I have any other option to take her back to UK on alternative route? I am thinking to apply for visiting visa for her from India to come back.
I am currently on ILR.
Does it effect to her MN1 in progress application if i will make her visiting visa application?
All Gurus please advice any other option.

Thank you all
