my 1 year old goes every couple hours during the day and can hold it a good 8 at night. When we first got her she was up every night at 3am peeing pooping and barking. She still barks when she pees or poops at night to let me know (usually 5 or 6 am, which is tough on weekends!)  
Im not sure how it works with one so young but try to get as much water in her during the day and less at night perhaps? Also I found putting a shirt in her bed with my scent seem to help her sleep longer Make sure you take it out during the day though! lol     |
