If he’s not ready he’s not ready. By all means keep trying if you want to, it’s your parental decision. But, after working in nursery with toddlers and kinder age for many years and being a parent myself it is sooooooooooo much easier to toilet train when the child is ready.
Toilet training b4 a child is ready causes so many issues with stress, anxiety, about going to the potty/toilet that it just makes toilet training take so much longer with accidents such as wetting or pooing in pants happening even when child is older.
What I’ve seen works from other parents, nursery workers and my own experience as a parent:
Look for signs of readiness.
Discuss with dc and listen to them. Are you ready to try to do wee on the potty?
Read picture books with characters that go to the potty or toilet training.
Make it fun! And be patient.
Rewards for doing wee on the potty.
In addition to the above: I bought 2 potties, 1 for her toys to sit on the potty with her or to play with in her room and 1 potty for her to sit on.
Children learn and make sense of the world through pretend play or role play. So, use that.
The reward system I used was a fun lucky dip where she got one surprise, small toy (like a toy car) for a wee and two for a poo.
She was 3 and she said she was ready and it went very smoothly and easily.
Over the years, every time I’ve seen/looked after a child who is being toilet trained on their parents schedule rather then on the child’s readiness, (and we are toilet training them during their nursery hours), it never goes smoothly. The child refuses to go to the toilet, becomes upset, has frequent accidents or holds on.
I’m sorry if it’s not what you want to hear.
