I have heard it can take that long too. What I plan on doing in August when I go back to work is to come home on lunch and let her out. I get a 45 minute lunch and only have a 4 minute commute. So when she is 4-5 months old she should be able to hold it for 3 1/2 hours at a time (I hope.) Hopefully, my plan works. Good luck training.
