Provided the child is born in the UK and has lived the first ten years of their life in the UK (with absences of no more than 90 days per year), they have an entitlement to British citizenship and cannot be refused.

Go through the guidance for Form T.

And also my second child is 7 years old,i want to know if my first child application is successful do you think my second child will be granted too or will he have to wait till he is 10 years too.

He will need to wait until he is 10 (assuming he was born in the UK).
