My 2.2 years old refuses to use potty. What is the best remedy?

There is no remedy as such but you'll just have to keep on trying without forcing. Each time u use the bathroom tell your child about it that this is where mamma papa go for toilet. Teach cue words to your child to signal bathroom time. Get a cute potty seat in a favourite colour that sits on the main toilet seat. Let it be there so that your child gets familiar with it
