Not a stealth boast ... genuinely worried I might get too thin or get osteoporosis or something.
Pre baby I was about 9 stone, toned hourglass. 5"2.
Didn't gain loads during pregnancy.
Now I'm just under 8 stone, no bum or thighs. DD is 10 months and under 9th percentile.
For medical reasons I've had thyroid checks which came up fine.
I try to eat plenty. I had anxiety for a while which killed my appetite but ok now.
Don't want to be ill. 
DH wondered if it was because pre baby I would go to the pub/cinema/gigs/shopping and snack more than I realised - plus I drank cider which is sugary.
But I'm queen of Costas now
.
Also will it come back after a year? ie to charity shop donate or keep the huge random size range I have...
