I have a 2.4 year old boy. most of the time he uses mobile for playing. How can I reduce this habit?

A. Pl visit mydvija you tube channel there is video about this wit hall techniques mentioned. Currently pl decide a technology time 20 min or 25 min. After that time there should be no mobile given. Don’t bother about crankiness or zid.. pl don’t give attention to any of this. Lastly u have to reduce using mobile so that we as parent have authority to tell it to kids
