Why does my baby kick my breast during diaper changes and when I change her clothes?

Re

My daughter is very long but, her legs and hands are magnetic to my breast. She always happens to find it. And it's impossible to change her without her having to kick or touch my breast.. And if I feel uncomfortable and irritated about her touching my breast she'll get really really fussy... I did breastfeed her but had to switch to formula at 3 months after being emotionally abused
