Came across another forum this morning and read a thread on there from a while ago.
The OPs basic issue was that she didn't want her step child to see her breastfeeding.
However, the thread ended up going off on a slight tangent and lots of posters were saying it was weird and exclusionary to be bothered about your step children seeing you getting changed for example, or in the shower, in your underwear etc..
With posters saying 'would you be bothered about your own child seeing you naked', 'they are just curious', 'it makes natural things seem inappropriate of you hide away'.
It seemed really bizarre to me. I have two step children and I definitely would not want them to see me naked or changing. The same way I give them privacy when they are in the bath or changing.
Fwiw, the OPs step child was about 7 if I remember correctly so not a baby or a toddler. My own step children are similar ages.
AIBU to think it's entirely normal for you NOT to want your step children seeing you getting dressed/naked/in underwear and yes even breastfeeding (although this wouldn't bother me personally) if you don't want?
The replies were very much suggesting we had a responsibility to teach children about these things, breastfeeding etc... And not make them seem wrong.
I think your privacy and who you want seeing your body is entirely up to you and no one should be made to feel responsible or like they should share that with certain people if they don't want to.
Just really surprised me
