No judgment, but I'll tell you what has worked for us. My son is 26 months old, I stay home with him full time. He started watching Sesame Street around 15 months, loved it! I would watch with him and we sing the ABC song to him. He has been introduced to letters, numbers, colors from very early on, with lots of access to books and us reading to him and singing and pointing out his name and the letters in it.
Also around 15 months we really started driving home the alphabet. Alphabet blocks, as he learned first words, we'd reinforce by telling him what letter it started with etc. By 18 months or so, he has started identifying letters. About 5 months ago, he got a big foam mat that is letters and numbers 0-9 in his playroom, he takes it apart like a big puzzle and just started saying more and more letters, so we used it as a game, can you find the...., what letter does blank start with. He LOVES IT! Best $15 ever spent. He now recognizes all but about 3 letters, we're now working on writing them, which he likes to do in the shower on the steamed up door. He also has fridge magnet letters, flashcards...it's everywhere! We use books to continually reinforce and turn everything into a game. He initiated a lot of it though, he doesn't sing the ABC song, but he'll see letters in signs or on the tv and has started recognizing words without pictures and even abstract places and point them out or pick something up and tell us it looks like an I or whatever. I figured, build up all the little factors til we get to actual reading. Using her name is a great way too, we have lots of things that say his name.
To some degree, I think kids have strengths and have to self motivate, but we jump started it by making everything about learning something in a fun way and we just continue to build on it everyday.
I definitely think if you're paying for pre-school, your child should be getting more out of it than the average kid. She should be ahead when she gets to kinder and though her particular learning style or development will play a part, you want to get what you pay for too. I would just say, do as much as you can at home, make it fun bottom line and create a love of learning and she'll be fine!
