I just sold my boy's xxs small items.

I know how hard it is to find things for that size as mine was less than a peanut when we got him. He had to grow into xxs. lol. I had luck with finding things at petsmart. Every store that I went to I would search thru the bins and got lucky a few times. You might want to check the for sale forum as a lot of people are having sales right now. Good luck.
