-How old was your child[ren] when you began to potty train them?
-How long did it take for them to get the general idea?
-Which method did you use?
-Any tips??
My child is almost 20 months old and I'll be starting tomorrow. I know she's not yet 2, but by time that occurs our next child will almost be here, so things will be pretty hectic.
20 months may be a little too early for your baby. I did not start to teach my children until 2.5-3yo. I was fortunate to start in the summer with both of them, and I took their diapers off and let them run around. By this age, they can start to feel the pressure of their internal organs, and if you are watching, you can see some distress beginning, at which time you can ask if they need to use the potty. Don't make a fuss about the potty. Just bring it home, set it down, explain about it - then leave it alone. I have seen people having all kinds of "potty parties", and it sets a high expectation on those kids, and so much drama about the process. They should know that this is a lifelong, simple way that everyone - mommy, daddy, grandma and grandpa, older siblings - do their business.
One thing that I did that worked with both my children was to take them shopping for underwear which had their favorite characters. They got to choose - and of course age appropriate. For your dd, maybe pretty pink ponies, or whatever she really likes. My children were excited about the underwear. They knew it was about growing up, and being a big girl/boy. I told them that when they could use the potty/toilet, they could wear the big boy/girl pants (LOLing at that).
You need a lot of patience, and not to get angry at the inevitable mistakes. Don't (please please PLEASE) don't "reward" your child with food or snacks or cookies for using the potty. I see so much of that. It's not good to reward with food. If my kids had a good day with the potty, if they had used it, then they could wear their underwear. They didn't want to mess up their underwear. So, it would have a positive influence the whole way around.
Remember btw, that your child will need to wear a diaper at night for a little longer, even though she is dry during the day. Maybe just a couple of months, but that "connection" in her mind will take a little longer.
Good luck whenever you go for it.
