I agree--Children's Medical Ventures has lots of stuff. We found them VERY expensive, however. We do buy pacifiers (3 sizes) and "wee-pee" diapers, the very small ones. We also got a lot of the squish-on things. We have a big one in the transporters to dampen the ride, esp for really tiny kids. Those ambulances have CR*P*Y shocks!!
We make our own swaddling cloths--22"square calico, hemmed. Some babies get too hot if you swaddle them in hospital blankets. You can position them prone and swaddled and in a nest. Try not to use the sling thing. As it was described to me, that kid has wworked for HOURS getting into that corner so he can feel secure, and the nurse comes along, lifts him back into the middle of the bed, puts the blanket between his legs and says, "Now, stay there!" He needs to feel enclosed to feel secure and relax enough to gt good sleep and grow.
I described on another thread that Grandmothers love to make stuff like swaddling cloths, and Moms can do the laundry. Brownie troops have to do a community project before they can get "promoted", and they can make some swaddling cloths (sewing project), and bring them in, let them see a baby thru a window if possible, and they're happy!
Volunteers can make Isolette covers. We had a nurse who was doing it for a evaluation project. We also got one of the little cuddling nests from CMV, and she used it for a pattern and made us some of those, too.
We have a second hospital"campus" that was built around ten years ago. we inherited a bunch of bedspreads from them that were the wrong size, so we had linen service come up and measure the incubators and make covers for us. They've lasted forever--not very pretty, but still going strong.
You can buy pre-quilted material at the fabric store, seam binding all around, and elastic loops to keep it in place. Make a slit in the front side so that you can lift up a flap to check on the baby when necessary. It doesn't have to be inky black in there just darker than the room.
Sometimes the incubator company makes covers to sell. Buy one, make a pattern, unless they're cheap.
Once you get going, other people will want to help the babies--it's something tangible they can do for them. People like that.
You also need a group of nurses to do the laundry. If you put it in the hospital laundry, adios... We don't have a washer and dryer in the unit, so we have a special hamper and people take them home.
