Im not a mum. I just went into the public toilet (to put up some single sex signs lol) and as I approached a man was just about to enter with a baby, I said excuse me I dont think you are allowed to use the ladies, he replied, pointing at the baby change sign, you can go in first if you like, I repeated, I dont think you can use the ladies, when I came out he had gone. Spouse said Im wrong, he’s allowed. googled and cannot see an answer?
