You should sit him on it first thing in the morning. You can try floating cheerios in it and have him target practice. I know a few people that used this trick and it worked. That's how both my brothers were potty trained.
With my oldest we started at 18m, not all the time. Just here and there and or every few months. By 2y9m old he was finally ready and with out diapers ever since! One thing I can tell you is that only your child knows when they are really....So dont stress about. And tip I can give you is once you are seeing that he is ready putting him on the potty every 30min. worked great with us and or just asking him if he needs to go....Giving candy when he does go, worked great as well!
I started just letting Isabella sitting on it once in the morning and once in the evening..... when she woke up/before sleeptime, without diapers if she peed/ she peed and i just said YEAY, just like mommy/daddy/ big brother/sister...... and once she turned two, i basically had her go butt-nakie at home..... i had a few clean towels for her to sit her bum on, and i took 3 days to sit at home, basically try to get her to go potty..... and she did within those 3 days she was potty trained. THERE IS literally NO USE to "pull ups" unless ya want your kid potty training for half a yr/ or ya want them in diapers til there four, then i suggest you start just sitting him on it, whether he goes or not, its ok either way, he'll just get used to a "foriegn object", so by the time he turns two, he'll know exactly what the potty is, and have him go butt nakie, for a few days while you will be at home, meaning no "trips shopping or anything just focus on the potty! :) She was potty trained at two. and im VERY PROUD. And no i dont think its just bc shes a girl, i know plenty boys potty trained at two, and i also know plenty girls AT AGE THREE dont want anything to do with the potty, and you know why?? its the parents fault, they waited too long, is all.
Well i can tell you girls potty train much sooner then boys. When he is ready you will know but you can start taking him to the potty with you. Also you can sit him on the potty while you are going and talk to him about it. Although both of my boys were 3 when they were potty trained during the day and 4 when they stoped wearing pull ups at night. Even though i started sending my 2nd boy with my oldest to the bathroom at 2 he was still 3 when it was said and done. I wish you luck.
We got a potty for our son when he was around a year old but didn't actually start sitting him on it until he was about 18 months or so, I think. It was more just to get him used to seeing it, and we explained what it was for, etc. When we actually started sitting him on it, it was right before bed. Eventually, we also started having him sit on it right after getting up in the morning. It took him MONTHS before he actually did anything in it....and the first couple of times were a total fluke, honestly.
He started displaying signs of readiness (ie. pulling his diaper off when it was wet/dirty,waking up from naps dry, etc.) when he was a little older than 2. By the time he was 2.5, we were really sure that he was ready. We waited until we had a week off from work to train him since we wanted to really be able to focus on it....and he was pretty much trained by the end of that week. Waiting until he was ready was really key. I won't lie: the first couple of days were rough and he had a few accidents. But once we figured out what was a good interval between visits to the toilet for him (45 minutes) and he got the hang of it, it went well and fast! We didn't even need a reward system....he just "got it" - and boy were we relieved!
I'd say that there's no harm in starting to familarize him with the potty, even sitting him on it as we did with our son. But if you wait until he's actually showing signs of being ready to train, then it'll likely go much better ;-)
Good luck!!!!
