I was really hoping to have my oldest son potty trained by the time my youngest son was born (don't laugh, but I was terrified at the thought of two in diapers), but while I was motivated to put in the work, he just didn't seem quite ready yet. (breastfeedbabywearclothdiaper.com)
We bought when our son was 9 months old because parents were pressuring us to have son potty trained by 12 months. (pottyscotty.com)
