I have a fairly standard 5-point harness setup for my high chair (Graco Slim Snacker), and I've noticed that as my baby gets bigger, his hips start to slide forward in the chair, and the strap that goes between his legs squeezes his crotch so hard that it leaves an imprint on his diaper.
I suspect that this is making him uncomfortable in his chair, and making him anxious when it comes to feeding him.
How should I adjust the straps so that my 10-month old son is comfortable? I've looked, but I cannot find any kind of guide related to this question.
