Congratulations on the twins Granddaughters, so lucky.

I believe I would just save those quilts for when they get bigger. I would probably make more for the NICS.

I don't wash anything in hot water and certainly not quilts.

Update: I washed the quilt in hot water and it came out just fine! The quilt was mostly lighter colors to begin with and I always prewash all my fabrics so bleeding was not an issue. It came out all crinkly and cuddly! Thanks for your advice and now...I'm ready to deliver to those precious little babies!

I definitely understand that you want to take those quilts for your own grandbabies but I would have concern that they could get lost in the hospital setting. When the girls are big enough, the hospital will probably request clothes from the family for them but be prepared that things happen in that setting. I'd suggest you make quilts for donation for other babies and reserve the ones you've made for your own. I have a preemie grandchild and the hospital even sent quilts home with the family. Some were of lesser quality and some were good. One that surprised me had a pieced top on a mattress pad--no back!--but it worked for the use intended and became an excellent tummy-time quilt for the floor.

As a grandma of twins who lived in NICU for 80 days, congratulations and the babies are in good hands!! Can I suggest machine binding, as I find the machine makes stronger binding to hold up to the many washings. Prayers for the precious ones!!
