Well what on EARTH took you so long? Only the first bottle babies? I've raised plenty here (unless a surogate mom can be found) and want to add one tip I don't see mentioned anywhere on websites that tell how to feed babies. I use the bottles with elongated tips, and with very sharp scissors I cut a small X from the tip, down toward the cap. This allows better milk flow and the babies don't get worn out trying to suckle with the 'hot needle hole" advice given most places. Also if they tend to suck the bottle flat while they nurse, slowly loosen the cap to allow air to flow back into the bottle. The younger the baby, the smaller the X that I cut, and as they get more proficiant at sucking I cut it a bit longer. And nothing beats having a dog to help with ahem 'diaper dooty'. They may not poop for a day or so as they're adjusting to formula that doesn't quite come from the Dairy Queen. I have a great recipe that I swear by that's easy cheap, nourishing and doesn't cause the diarrhea that KMR can cause. But seeing as you just have two wee ones, KMR does the trick. For larger litters I use the homemade formula that was published in Cat Fancy some years back. Have fun Meewmie!
