Create a Potty Training Schedule
I can't get my 2-year-old to tell me she has to go before she actually goes. What can I do?
At age 2, children are still learning their verbal skills, so you can't rely on them to tell you their needs exactly at the moment they need them. So spend a few days figuring out your daughter's potty schedule. She's pretty young and is probably having a hard time recognizing her gotta-go signals, so it'll help both of you if YOU figure out when she's going to have to go and preemptively put her on the potty.
Once you have a basic idea of when she's going to have to go potty, Try using a potty timer. Buy a kitchen timer and decorate it together with stickers. Set it for 2 hours (or whatever time frame works) and when it dings, it means it's time to go potty whether she feels like she needs to or not.
Remember to reward her successes so that eventually she'll be able to recognize her own signals and tell you she needs to go on her own. Bottoms Up!
