Could bladder training cause uti?

I believe so: Little children don't understand need to relax pelvic floor muscles or urinary sphincer to urinate. Parents may suggest that child pushes urine out squeezes abdomen. Either way child will then contract pelvic floor musles whilst trying to push urine out. This leads to poor bladder emptying ; utis. My advice is give access to potty ; tell child to make shhhh. Child will then try to duplicate sound.
