So I'm getting ready for DD2 and I have 24 BG4.0s that I used daily for about 2 years with DD1. They are in great condition other than the elastics so I know I need to refresh. I can sew and I know the elastics in the BG4.0s are pretty easy to replace, but I came across this YouTube video about tightening them without sewing and it would be a lot quicker.

I did this in about 2 minutes on a diaper this morning so you can see the difference. Do you think this is a reasonable approach if I want to get another 2 years out of these diapers or should I bite the bullet and just replace the elastics all together? Thanks!!
