The Sleepover Pajamas took a little longer to make because I chose to include the ruffles. I opted for snaps instead of buttons, and I shortened the sleeves, like 3/4 length sleeves, since we always have problems with pajama sleeves getting too involved in breakfast.
The nightgown was very easy! I just lengthened the blouse top. It took about a yard of fabric, total.
I hope this is helpful to those of you who sew for your kiddos!
