My sister in law and I got together several years ago and decided we would have 2 boys each and we would mix them in with the ages and then hand me downs would work well.....yea right!
My sister in law and I are very lucky in that we do have 2 boys each and their ages mix together quite nicely. She has Ellis who is 8, I have Ben who is 5, then she has Harvey who is 41/2 and I have Alex who is 31/2.
It also means that when Ellis is turning 21, the same year we will have an 18 yr old, a 17 yr old and a 16 yr old! Imagine those 4 together in the same house for the weekend!
Not that we planned any of it, but hey, that is life.
I have a friend who has a 10 yr old boy and she is wonderful in passing on old clothes to me, I have happily kept them in the cupboard until Ben fits them, but then decided that in fact Claire could get more use out of them with Ellis, so they now go there and because Harvey is slightly bigger than Ben, even though he is younger, as long as they are still in good condition when they have finished with them, then my two still get to see them as well.
So hand me downs are doing the long run with all of us.
