At daycare they may have a set schedule that she has gotten used to as well as the fact that her friends at the school are doing the same things.
at home,she is after more of your attention and figures this is a good way to get it for at least that 1/2 hour is to wet herself.
Try using plastic panties over her regular panties,she will find out pretty quick that they don't feel all that comfy.if you stick to your guns and let her know,when she stops peeing at home and go like she does at school,she can stop wearing them.
I know you may think this a bit harsh,but it is not,I have used this manner of training for years,and have found it very successful.
hopeful_mom4, Hi and welcome to the Toilet Teaching board.
Have you talked with the daycare center and asked what they are doing? How often do they do a potty break/ what schedule do they follow. This way you can do the same process they are doing. It is usually much easier if the same process is followed.
When your DD has an accident at home have her help clean up. Have her rinse out her clothes, and put them in the washer/ or where you would to have them placed. I hope this helped. Please keep us updated on your Dd progress.
