Ok not really an AIBU, but if you do have baby clothes you no longer need (or any children's clothes in good condition) please consider giving them to your local women's refuge.
I know it's so easy to just take them to you local charity shop, or put them out for one of those door to door charity collections, but a donation to a women's refuge can make a real difference straight away.
I'm lucky that I've never had the need to use a refuge, but I've seen so many stories on here from women who have fled abusive relationships and the great work that the refuge's do.
I simply Googled Women's Aid and my local town and got a number to call. I asked if they were in need of baby clothing donations and the lady told me that they had a few women in the refuge with young babies who would be extremely grateful.
Just something to think on next time you have a clear out.
