there can be many reasons and I will say my thoughts on just a few.
1. your toilet trap of the bowl is clogged with debris (toys, balls, etc)
to fix = snake out toilet bowl or if necessary pull toilet bowl and snake backwards threw trap.
2. your tank flush flapper is closing to soon or your tank water level is not at right height
to fix = change flapper or adjust water level height
3. your toilet arm before the vent is plugged because of back grade or debris clinging to the side of the drain pipe
to test = pull toilet and run toilet water supply full on down threw toilet flange and see if any back flow.
4. your toilet main line is clogged from backgrade,roots,damaged pipe,etc but will let other fixtures slowly drain
to test = camera toilet line from toilet flange out to street or septic or if no camera available then fill tub full and lav full and drain both at the same time and look at your lowest fixture trap to see if any back flow exists or open clean outs and if possible to see water flow .
