I'm 5ft2 also! I'm small boned too, have always looked in proportion and not too thin, just small.

Before we tried to get pregnant, I was on the pill and would be somewhere between 47-49kg. When I came off and gave up alcohol, I dropped to 44 so I had to start eating more, and having a few wines (when not in the 2ww). So I was 45kg or so when I got pregnant, went up to 59kg at 41wks, then back to 48kg 10 days after the birth. Ridiculous, but I've always been like that, the weight tends to fall off a bit easily for my liking (not great when you get sick).

I'm happy to be anywhere from 45-50kg generally. I'm a bit 'softer' now than I used to be as I had bad SPD then a c section, so my exercise level isn't back to 'normal' yet. I have a rectus abdominus diastasis still so my waist is a bit larger than before. I'm generally a size 6, and still am, but the boobs don't fit my size 6 tops at present unless they are full of lycra. Limits the clothes I can wear as I used to wear quite fitted tops, and with the boobs 2 cup sizes larger on my little frame, they don't go in those shirts anymore!!
