My nephew came over today and I noticed he was wearing an outfit that I had given to my sister years ago when my own son grew out of it. It reminded me of the times when my son was still a toddler. 
That's amazing, how old is your son these days?
He's 14 now. So it was some time ago! I held onto the clothes until I found out my sister was having a boy. Brings back so many memories seeing the outfit on my nephew.
That's nice that you can share things like that, it seems like your family is very close!
We are. We're a pretty tight knit family. It's pretty common for us to pass around clothes to one another too, just to help out.
