Nope thats it. I start the kid with the lambar nipples on pop bottles for their colostrum, then their colostrum milk, so by day 2 or 3, I have them taking it without help.....I then use a bucket I have lambar nipples only about 4 inches up from the bottom, so there first feedings the milk in the bucket is right at the nipples, takes hardly any sucking at all to get a mouthfull of milk. Don't expect newborns to suck milk out of a 5 gallon bucket with just a quart of milk in the bottom, they wear themselves out way before they get full. At first you have to help them, sometimes, especially boys for some reason you have to help them over and over and over....it's where a holder helps. My husband simply uses rebar and makes a hoop the size of the bucket, a flat piece to stop the bucket from falling down to the nipples, and then welds it to a rim, or now he makes these big rebar stars so they simply can't tip them over when larger.
I can snap photos if you want to see the holders.
When the kids are little I simply use doubleend snaps and snap their lambar to the pen, I have photos like that up on facebook. Vicki
