I don't really know if this is unreasonable or if I'm just being sensitive. 
I'm on maternity leave. Things are good, moving into our first mortgaged home and baby fine... the problem is my mum.
I moved 5 mins away from her to help with childcare when I go back to work so we're seeing a lot more of each other at the moment.
She keeps buying me Size 16 clothes and even an 18 the other day.... (really thoughtful to get me clothes, I buy more than enough for myself but she still feels the need to pick stuff up for me and my sisters sometimes)
I do politely mention that she doesn't need to buy me clothes and that I'm not a size 16...I'm a 12. I was a tiny 8 before the baby.
Along with the bigger clothes come the slide comments about my weight and appearance. It's beginning to make me resent her... my sisters join in too.
Partner loves my body and says he likes the bigger love handles and bum! I wasn't that concerned until the constant remarks from her.
It's not just weight comments, she always criticises my parenting and what I'm doing Day to day.
Writing this having a sob, she never used to be like this.
I feel ungrateful and rude about obviously not being able to wear the clothes, yet angry and sad about the way I'm treated. Am I being unreasonable? I don't know what to do
