Visit to Sandakaphu with 4 years old girl

Hi...I am planning to visit Sandakaphu and Phalutwith along with my daughter (4.5 years old) and spouse on this october,2018.

I dont have any plan to trek anyway..i would definitely hire the landrover from Manevanjan.

My question is " whether my daughter can manage the altitude or not? I dont want any adverse physical condition for her.

Should i cancel the trip or it will be alright......please suggest.
