One suggestion I might make is to avoid straight line diagonal quilting. I made the mistake of doing that on my SIL's quilt and he has broken a lot of the stitching. He tends to kick or push against the quilt with his feet and that stretches it on the bias. The quilting stitches do not stretch, hence the breakage. So maybe avoid diagonal lines on your kids' quilts if you think they will be rough with them.
