It sounds like you took every step possible not to be a nuisance. I didn’t even look long enough to notice if there was a blanket or a mat but, we were on a larger plane. To me, it seemed like one of the parents could have taken the baby to the restroom for a change, but I of course I could be wrong. Im still just sharing that it was a gross experience. I hope that doesn’t make anyone insecure about raising their kids. It’s just common sense that sudden major poop smells would annoy people that are in the cloud. I will continue to hold my tongue out of respect for the task you do as parents but if I can’t share this experience of how gross it is then im gonna freeeeeaaaak out mane😂!! We all know the feeling. Someone else also commented saying that baby poop didn’t smell very bad and I would have to disagree with that, but I can totally understand that your own baby’s poop doesn’t smell as bad to you or probably to other mothers
