A., we learned about gDiapers when our daughter was approximately one year old. We went on to use them until she was toilet trained at 21 months.
We love gDiapers! They are so wonderful for babies and the most environmentally friendly choice. Also, not to be forgotten, they are cute :). We loved the reusable covers and would sometimes use the covers with cloth inserts. We used to live in a house built in 1922 and never had an issue flushing them. Traveling with them was always convenient. If I was ever unsure of whether or not a specific toilet would flush the flushable, I would just throw it away; they are still produced in a very environmentally-friendly way, so there were still benefits even if it did end up in the trash.
Our dd was very comfortable in the diapers and she never had any rashes. If I think of anything else, I will send it your way, if you have any questions, please feel free to email me.
Best of luck to you, S. (mom to Saffron, 2.75+)
