My son has been in pull ups since he was 6 months old (I just found them more convenient) but if you’re trying to potty train, pull ups are actually counter productive.
We switched around 10 months to a pull up because she moved a lot. We just potty trained her fully at 15 months and now she’s in underwear. I was planning for 18 months but it happened fast, pull ups were dry and consistent so we made the switch and it’s early but we are happy 😃
My daughter is two and a half and starting to mention the potty and sitting on the potty occasionally but not peeing yet. I have some pull ups but I still have diapers so I have switched over fully. My older daughter didn’t potty train until 3.

Whichever makes changing easier. They tended to get full similarly and pull-ups didn’t give us any potty training benefit, we only make progress there with underwear.
@Larissa is she in diapers or pull ups?
