I personally think it is great to start training before 2 but I just don't think a child before the age of 2 has the vocabulary to truly be trained. If you can leave her in panties and just send her every hour then great but if not then just go with the pullups. There is nothing wrong with pullups. Some children take longer than others and I don't think pressuring them to much to train before age 2 is necessary. It is all with what you are able to do during your day.

I trained my daughter in pullups during the day (during daycare as I have carpet in the basement) and we did panties in the evening. I started introducing her to the potty at 18months. We did pullups for naps/night until about 3. At 2.5 she was completely in panties during the day.

Do what works best for you. Your daughter will get it but she is still young.
