DS2 is the classic hand me down kid
My DH just the other day asked me to go out and shop for him
DS1 short and skinny DS2 Little and stocky. He manages to fit into most things still.
Some things are really hard to get so if I had them for DS1 I would keep them no matter what, like onesies without the envelope shoulders.
Things like socks and I kept DS1's old jocks for TT DS2 (very handy!)
I went through and picked all the best stuff and kept it, put it in boxes in the right sizes and anything else either got thrown out or given to DH to use as rags.
And if they were still ok just not what I wanted anymore...Salvo's.
