size 6 boys clothing

I am looking for some size 6 boys clothing. Jacob is growing so tall. He really needs pijamas and honestly we don't care if the match or what not, just comfy things to sleep in. He does need pretty much all other types of clothing as well. I will head to Value Village to get clothing if need be, but I thought I would see if anyone has some to hand down to us, first.
We are so grateful for all the help we have received for clothes for all the children!
