Some Students have asked about tuning instruments at home. In the winter it is common for violins to go very out of tune to the point of strings looking broken and very loose. ONLY Parents should tune the violin at this time
I do not expect you to buy an expensive tuner. I recommend the APP- “Violin Tuner Free” on the app store. It will sound each string for you and you can match the pitch as you adjust the pegs and fine tuners.
