In the 70's there were mostly cloth diaper and toddlers are trained by 18 months. This has been a challenge for us.
We have tried different techniques to make this work. One is singing the 'Where's the Potty' in tune of Are you Sleeping? , another is doing it with Baby Signs (using hand signals) , and lastly is by talking to her to bring her toys.
Sure enough when I told her to bring her dinos to the potty, well this is what she did! :)
