> having access to iPad helped my daughter to learn way more than I thought she could at that age (e. g. English names for colors; count in English and the alphabet song — before she even was three)

While that may sound awesome, I'm not so sure it's better in the long term. Your daughter would've learned the English names of colors and the alphabet eventually anyway. OTOH using phones and pads changes our brains, making us worse and worse at keeping our focus. We become addicted to that something is always changing or moving until reading a book becomes hard. I'd rather start from the other side, reading a lot of books for the kids, letting them learn at a slower rate but with retained ability to focus.
