My snowsuit from when I was a baby 42 years ago has been worn by my 3 children too, from my 19 year old down to my 17 month old who was still wearing it. I caught a seam on something last week and it ripped.
My mother in law is great at sewing and fixing things, dh asked if she could fix the seam.
He went there at lunch to pick something up and she handed him a new snowsuit she had bought for dd as she had chucked mine in the bin as it was old and she thought she would replace it 
I’m not angry at her at all. It was a 42 year old mothercare snowsuit that’s been through 4 children (it was still in good condition though and quite retro and cool). She doesn’t know it was
sentimental to me, We should have said not to throw it if she couldn’t fix it.
To anyone else it was a bit of old shit but it’s was one of the only things I had left. My mum died when I was little, my dad is now 85 and in a care home with dementia, we’ve totally lost him
now, who he was has gone. At the start of his dementia, he started chucking away so much stuff and I didn’t know. So many family photos, videos all gone.
He’d always kept that snowsuit though as my mum bought it the day she found out she was pregnant with me, and he remembered laughing at her because she had bought it in 1 year old size rather than newborn because she was in such an excited flap on the way home from the dr. He loved seeing my older two in it. My littlest dd, he was too far gone to even register.
Plus, I had it in my head that if I was ever l lucky enough to have a grandchild one day, I’d be that annoying gran who passed it down.
I need to get a bloody grip, don’t I. It’s a fucking snowsuit, not a royal christening gown.
