Press small clothes with a hair straightening flat iron
Every hack that reduces ironing should get an immediate pass to the front of the line. I'm satisfied when they're clean. BUT, I have dealt with the bow problem Heidi mentions, and she offers a brilliant solution:
I use a flat iron (for hair straightening) to iron my girls' clothes. I hate ironing and avoid it as much as I can, but sometimes a piece of clothing will have a wrinkled bow, or a cuff, or something that needs a press before it can be worn. So, instead of dragging out the ironing board and iron, I plug in my flat iron and the dreaded chore is completed in no time.
Now, granted, my twin girls clothes' are small because they are only 3 years old and barely wear a size 2T, so I'm not sure how this will work as they get older. But it is definitely a good hack for small clothes.
