I have a friend (an older quilter) who sergers all of the seams of the quilts she makes for her grandchildren (they are all boys). She said that she did not want them to have issues if they did not gently care for the quilts.
The only time I have had issues with my 1/4" seams pulling out has been when I used some of the homespun fabrics that came out several years ago -- they really raveled. I stay stitched about 1/8" in before I sewed the blocks after I saw what was happening.
