If she is kept dry and if she comes to learn that eliminating requires a special place, she will consistently work with you and as she gets older, she'll tell you when she needs to use the toilet. Learning what your baby's signals look like will get easier. As you get to know your baby better, your confidence in yourself will increase. You don't actually need to keep your baby diaperless all the time. You can always put diapers on her between visits to the toilet, especially when you're away from home.
Bowel movements are much easier to manage.
They happen more infrequently and the signs are more obvious. You might notice that she will have to go at the same time every day, such as first thing in the morning, or after eating a meal. As with peeing, you will get to know her patterns. The obvious sign of a bowel movement is a tightening of her abdominal muscles and a straining or grunting sound. At any rate, you usually have more time to work with than you do with peeing.
