Focus Setting Question - Auto Setting vs Manual

[g gunna]

Hi. I'm new here and to Fujifilm camera. I have had the XT-30 for almost 7 months now. Bought it mainly to take photos of the little one.

I have some questions regard the focus setting for this camera. 95% of the time I'm shooting indoor photo of a fast moving child. However, I can seem to get the settings right.

Here's my setup and setting

1. 23mm f1.4 or 16mm-55mm f2.8. So lens is not an issue I think.

2. Auto 1 - Max 400 ISO/125 shutter minimum. But when I shoot, it always drop below 125. 

3. Focus points - the camera is not focusing on the face fast enough. Even when the child is still for a long moment.

appreciate any help at all.

The first thing to do would be to increase the maximum ISO - try 3200 or 6400 - especially indoors - you might find noise is still acceptable at those settings - better than blurred images (the other alternative is to increase the light!)
