What age was your child fully potty trained

My daughter is almost four and isn't potty trained yet. She's special needs so she's a bit delayed, which might be contributing a bit, but I'm in no rush to force it upon her.

Mines 3 and only day trained. Occasionally has a dry pull up at night.

A few months after he turned 3 but we'd tried several times before with no luck. He was just ready and basically trained himself in a couple of days.
