You may be better off shooting kids one of more recent Sony zooms than the longer primes.
AF with the Sony FE 1.8/85 has been pretty unreliable for me for moving subjects especially wide-open. It is one of the lenses that supports 120 FPS AF-C tracking, so maybe it works better on the non-7 series bodies? I don't find the Samyang 85mm F1.4 AF to be any worse or better. I haven't used the Sigma 90i enough to give an opinion about its AF performance. It is low amount of breathing helps when focusing outside the center of the frame.
