Childish clothing. This company is owned by Skye Hoppus, the wife of Blink-182's bassist Mark Hoppus. They have lots of fun, punky clothes for boys. I shop there for my daughter and my nephew and always find something that gets a lot of compliments.
The consignment idea on the previous answer is god . I have done that too. Many times people get gifts which fit the kid in the wrong season so they consign them.
Also check out Hanna Andersen. Gorgeous clothes - pricey but they last forever. They wash really well. The crap clothes you get at Old Navy and Walmart etc. never wash out - one stain just wreck them. But these clothes wash well.
Have fun! I love baby clothes!
