Hi, A..
With my older daughter I mostly used cloth diapers (she was highly allergic to most disposable diapers) and she was waking up dry at 9 months, but she was not ready to potty train. I will say that using cloth diapers made potty training easier for her. We also used training pants with diaper covers (just in case she had an accident). I think that by the time it was all said and done she was 2 1/2. She, too, loved footie jammies, but we switched to night gowns when she woke up to go to the bathroom because they were easier for her to do herself. My last daughter didn't wake up to go potty in the middle of the night...thus she wet the bed long after she was potty trained. Again we switched to nightgowns when we started potting training.
I have potty trained lots of kids (mine and others) and my best piece of advice is to not get too stressed out about it. It will happen when she is ready, if you are stressed out, she will be also. Push too soon and it will end up taking longer. Introduce the potty chair (if that is the route you are taking) when she seems curious or if she is staying dry for long periods of time...let her sit on it with her clothes on, etc. If you aren't going to use a potty chair, they make seats that fit on the toilet so that the opening is toddler size (about $7/$8 at Walmart/Target). I have used both successfully.
Praise, praise, praise...three words that cannot be said enough. Praise her for her efforts even if she doesn't go. Praise her if she tells you that she wants to go. Praise her if she does go. And don't punish her (or use criticisms) if she has accidents.
One other thing that seemed to help the potty training over the years is "positive peer pressure" or, in other words, having a buddy to potty train with. For me it was a neighbor girl that was 6 months older than me and at 18 months I told my mom that I didn't want to wear a diaper anymore. For one of my girls, she wanted to be like her older sisters and wear big girl panties. Many of my childcare children have had someone else to potty train with (sometimes it was friendly compitition).
I hope that something I have said helps. If you have any questions let me know.
