I am sure the talented ladies will be able to help you with schedules.
The last thing I want to do is to be negative, but it took my lo a long time to be a good napper. I studied the Baby Whisperer books, this site, and wrote tons of questions. I tried a lot of the techniques.
Like you mentioned, I think it was encouragement, her body learning to calm down, self soothe, & put herself back to sleep when necessary.
One friend said, do what you can to help your lo learn to nap. BUT.... at the end of the day don't beat yourself up. (Some are better nappers than others. I am convinced of it. I truly followed every rule & advice, I could. )
So that is my advice to you. Your lo is still pretty young so if you have it in you try not to give up. If you need a break then take one for sure.
Personally, I think you are coming out of the tough stage so keep your chin up!!!!!
You will be getting more sleep so it will be easier for you to keep your patience. It will get better. BELIEVE ME. ::)And, you have a lot of support here!!!
