Right now I'm putting our savings into an ING account, it's currently at 4% APR. I'm also reading "Mutual Funds for Dummies"

to improve my understanding of other investment options, I hope to start an investment account soon.
In the meantime, I like having our savings in the ING account. It's quickly accessible in case we need it for an emergency or large purchases (midwife, birth tub) and it is a relatively high interest bearing account. Right now it's bringing in about $13 a month in interest - might now seem like much, but it's a lot better than the savings account at my credit union. We will probably keep our emergency fund savings in there after we decide on an investment account.
