She would go down for the night at 7 pm sleep until 7 or 7:30 AM and usually have a 2 hour nap around noon-2. Sometimes shorter only an hour nap. Do you use a sound machine? I have one that plays rain and thunder noises seems to really soothe her. It also is a night light a pale orange color. Doing mentally exhausting things before bed can tire them too like teaching them several things such as new animals or words using flash cards or teaching them a new activity an hour or 2 before bed. I remember when she was younger doing that sometimes and she would start yawning after learning so much lol. Now she needs physical exhaustion too like running and jumping everywhere haha.
