Good Morning. I would like to offer this article as a good guide to your child's sleep needs. Children at your daughters age need about 14 hours of sleep with about 11 of those hours coming at night. I would suggest working first on getting your child to sleep later in the morning. I would start by moving her evening bedtime back about 30-45 minutes. Her body should respond by sleeping later in the morning. It may take a few weeks to see a change in her schedule. I would then start moving her nap a little later in the afternoon. Since she will be sleeping later adjusting the nap time later in the afternoon (after lunch is a great time) should compensate for the time she is sleeping in the morning.
I hope this information is helpful to you and your daughter. Don't worry about not doing things right as a parent. Part of being a parent is learning things by trial and error. Hang in there and be patient :)
If I can be of any assistance please don't hesitate to ask.
