Hi R.
Some kids don't need as much sleep as others. I always was one to let them be on their own schedules.
When they didn't want an AM nap, I hoped for a longer PM nap. Sometimes it happened, sometimes not. I found just when I figured out what their schedule was, it changed.
The MD told me as long as they did not show signs of sleep deprivation, all was well. Yes, you can be in sleep deprivation w/o them being in sleep deprivation. We were!! Our children never were. Our younger boy only slept/sleeps 2 hours in 24. Not sure exactly when it started maybe around 2y, but his time got shorter and shorter til we got to 2 hours in 24. He climbed out of crib at 5 mo. He would sit and let me read to him, or sing songs, or even puzzles and playdough. Today, he takes care of his son so his wife can get some sleep. Our older daughter slept/sleeps where she can and about 4-6 hours in 24 and although I thought if I ever had another kid like our son I would get MD to do something. They don't because she is perfectly "healthy". My other 2 slept about 10 hours at night and never napped much, but I was thankful for the 10 hours because I knew what it could be.
God bless you.
My advice choose to accept their schedule because to have a power struggle causes rebellion, and where the rebellion shows up is where ever they can be in control. Potty training, activity, eating to name a few.
Write me and we'll visit. What does your mom say? She might have great stories about you. I love to share mine, she probably would to, I hope that is possible as you are young enough to be my daughter, write me OK.
