Just different enough from Ava's bedding to be fun and new but still very girly and quilted and toddler friendly too. I think I will just go with a twin quilt this time because I know that most likely Lilly will be in a twin trundle bed before two (her room is smaller than Ava's so she won't be able to do a full bed like Ava has). Also, I never used Ava's baby quilt for anything other than hanging on the side of her crib. The other thing I am debating about is the bumper because I had to take it out of Ava's crib at about 7 months when she started pulling up on the crib's sides and then using the bumper to stand on.
I think a great thrifty idea for a nursery if you are watching the $$ is to splurge on or register for a twin size quilt you totally love and hang it folded on the side of the crib and then buy the sheets, bumper, and skirt from somewhere inexpensive like Target in coordinating colors or prints. You can use the twin quilt for a long, long time even when your child moves to a larger bed.
