You are not alone. You could be describing my DD (age 4). She is always on the cliff ready to jump into the deep dark hole. I wish I had the magical solution but we are still trying to figure out how to get her past this. Since DD does go to school but isn't getting challenged we have added in 'homework' for when she gets home. I've been pleased with her reaction to all of it. She is excited to do the homework and yesterday even asked for some math. Given how long her school day is we are focusing on reading everyday but on weekends we add in some math. Before starting all of this I gave her an assessment and she is clearly in 2nd grade level work. The sad thing is she was basically there at age 2 but because I freaked out about a lot of this and didn't want to 'push' her and given her personality she didn't move forward. I can happily say that our homework idea is moving her forward and it looks like she is starting to thirst for more. Now if we can figure out how to convince her to speak up in school about wanting to learn more we will have really accomplished our goals.
