Mac, I did some booties for the hospital to give to new moms. In the Military they often don't have family around so it's nice to get a little something to take home. I used to crochet boys booties that looked like basketball shoes (Hi Tops) and baby girls shoes that looked like mary Janes with a tiny pearl button..not advisable now I guess.
But my favorite thing to crochet was a tube that fit around a small (short) bottle then add two elephant ears to the sides.
The bottom had two round crocheted balls about the size of a tennis ball.
You put the crocheted elephant on the nipple end of the bottle (the nipple forms the trunk) and a baby can lay in your arms and drink..when the baby lets go of the nipple the bottle will rock back and not drip all over baby. That leaves a hand free for mom!
Here's a picture of an old one, but the nipple for the bottle is long gone (I just used it as a form.) Also there are no instructions as I made this up for my 1st grandson..G'ma couldn't cook and clean while feeding him!
