Like I know a lot of kids aren't even close to being ready before they're 2, but I feel like my son is getting super close!
Then I was talking to my grandma about it, because I was curious to see what she said and both of her kids, my aunt and dad were potty trained before they were 2!! She said my aunt was really easy and she could say more words than my son. But all she did was put cloth panties on her and she peed in them and never peed anywhere but the potty after that (she didn't like the feel of her pee on her legs and skin)! My dad was 19 months old, and she had him potty trained too. He had a couple accidents after but for the most part, fully trained.
My son is 17 months old and very smart. He knows quite a few words and he just tries to learn more everyday. He's very 'talkative' with his gift of baby gab.
And he's also very curious about the bathroom and other people going potty! Sometimes he just wants to be in the bathroom when other people are in there XD
My mom and I were joking with him, because he's always so obvious when he's pooping. He just grunts and grunts and farts until well, you know ha ha. Anyway we were grunting with him, encouraging him pushing, and he just started grunting louder. So I set him on the potty, and he kept grunting, but I don't think he was ready to go yet.
It was still another hour before he went and needed his diaper changed.
Anyway, I think I'm going to get him a new potty seat next month and start working on it. I definitely don't see any harm in it

Re: What's the youngest age to start potty training
Baby 2 EDD 7-18-14
ETA: At the younger ages, I'd suggest getting a little potty seat as opposed to a bigger toilet insert. DS only recently started feeling comfortable on the regular toilet - he still prefers the potty that is "his size."

The one thing I will say is whenever you start, go all in and don't go back. Trying and stopping and trying and stopping just confuses kids. If yours is showing interest, go for it! Skip the dipes, pull ups... go naked, clean up the messes, get your floors cleaned in a couple months
I was planning to start in the summer when she turns 15-16 months old but the plan has changed, I'm due our second baby in July so I think I will put off potty training around September / October. I definitely want to get started before she turns 2, even if she doesn't pee or poo in it for ages.
I won't be getting her to clean up her own accidents though, I don't think that's a good thing at all. I have taken a relaxed approach about everything else so far and she's been an easy baby to look after so I think a relaxed but consistent approach to potty training will be good too.
