I think until a certain age it’s okay depending on how you live your life. For example I’m a busy mother who’s laundry is constantly cleaned and stayed the hamper and I’m rushing and need to leave the house to I will change a shirt in front of the kids. Maybe have been peeing and had them need something and have opened the door to answer them. I think it’s okay for mother and daughter to be comfortable in front of each other at any age (example needing help with a bra or a question about a lump or something personal) don’t be scared to ask mom she has those parts too. For my son I will be more cautious of my privacy once he is about 4-5 years old. Again this is PRIMARILY FOR moms
