Genuinely curious about this. I only really thought about it yesterday whilst in town. My DS is 8 months and I went to change him in Debenhams, which is where I normally go as there isn't many baby changing facilities in the town centre.
Our store has a separate room for baby change which also has a toilet in as well. So if I ever need the loo, I always go there so I can change DS and go to the toilet as well.
However, yesterday the baby facilities were out of order and I needed to go to the toilet. I tried going in the women's but my pushchair has really big wheels and I couldn't get or fit it through the door.
I figured I could have used the disabled but you needed a key and I didn't feel right asking for one because I don't have a disability. In the end I just left early and went home. There isn't anywhere else in the town centre that has a toilet with a baby change in.
Has anyone else found this a bit of a PITA?
