For those clothes beyond what you get from people here, check out your local children's consignment shops. I've gotten most of my kids clothes from them, and usually they are in fine condition, especially for infants and toddlers. Most also will give you store credit which is often more than they will give you in cash, if you consign outgrown clothes there. Then you can use it on future purchases. It's been a great deal for us, I've saved a lot of money on clothes this way, considering we don't have a lot of relatives who will give clothes as gifts.
There are always garage sales too. Check the newspaper. But be aware that a garage sale that lists "baby clothes" in its ad tends to get a lot of people pretty early in the day. Almost like a hoard of locusts at our last garage sale!
Tell us something.: I used to be a regular then I took up the bassoon. Bassoons don't have a lot of chiff. Not really, I have always been a drummer, and my C&F years were when I was a little tired of the drums. Now I'm back playing drums. I mist the C&F years, though.
