Aw hun, poor you :( I know you want things to be perfect but remember babes will likely be sleeping in your room for the first few months, and as Annie Brooke says, bumpers and quilts are a smothering hazard for babes. My baby boy is 4 weeks and is still in his Moses basket in my bedroom, his cot is in his room and is all made up with the bumpers and the quilt etc but he won't be in it for another couple months - to begin with we are putting his moses basket into the cot so he can get used to the bars, then we will do the transition into the cot itself - once that happens, the bumpers and the quilt will be out and babes will be in his little sleep bag, loking tiny inthis huge cot lol x
I'm sorry it made you unhappy. Crib bumpers are no longer suggested for use in the crib, they are a smothering hazard. I used mine around the bottom of the daybed in my son's room. (The daybed was left over from before there was a baby in that room, and I needed to leave it where it was, and the bumper acts like a nice looking dust ruffle for it and makes it look more childlike. Otherwise it was a big, clunky bed in a baby's room.)
If your crib is against the wall, you could do the same with the bumper, use it as a ruffle of sorts. Space it as evenly as you can going out both directions evenly from the front center, so if the ends come up short it is no big deal.
As for the quilt, put it on the mattress if you would like, but when the baby comes, again, no quilts in the crib as they are also a smothering hazard. I wound up with the quilt that matched my son's bumper just being folded over the crib rail, and I would move it at night when my son went to bed.
What does a baby sleep in? A swaddle or a sleepsack, on the bottom sheet with no pillow, top sheet, blanket, or quilt. As the Girlfriend's Guide to Pregnancy says when talking about cribs, "If it sounds like your baby is going to be sleeping on something as bare as the benches at the bus station, that is about right."
