They weren't pushing young kids to get baptized back in my day (late 70's), or at least not in the KH I went to. 16 or 17 was the common age for kids to get dunked at our KH, slightly younger if they were born-in keeners. But around that time, my doubts had become so strong that I knew the JW life was not for me.
From about age 17 to 19, I put up with some pressure to make the commitment. A couple of the hardliner elders were pretty passive aggressive about it to me, and sometimes not too passive either. My mother often got quite nasty about my avoidance.
It was stressful and sometimes miserable but getting baptized felt like I would be trapping myself forever. Something about it just scared me silly. I'm glad I listened to myself :-)
