I also agree that we should not deprive them of life experiences. If you are doing flashcards for 24 hours a day in a room with just mom, no baby will ever enjoy that. As Linda says, flashcard only takes 3 mins a day, for the rest of the day, you can do whatever you want with your baby, games, Ocean park, reading, singing etc.
The formula I gave is just the way I think a lot of parents think, it may be a little naive but you cannot say it's wrong. I do not agree that formula is the best way to go but I was just giving it as an example that we should not never judge others as they must have a reason behind doing things even if it is not in our opinion the 'best' way.
I do see a lot of kids who had a 'happy childhood' but because they were 'too happy' and did not experience any pressure at all throughout their childhood, that when they face the 'real' world, they are in shock. They cannot face any challenges and tend to give up very easily. I have interviewed and employed so many of these kids that it is sad to see the new generation like that.
There are life long arguments about the 'best' teaching methods for children and I am in no position to challenge any of these experts Montessori, Doman, Shichida, Suzuki, Steiner etc. However, I just think that doing something the whole family enjoys is, for me, the best way to bring up my happy child.
As I mentioned before, I was raised without many toys (as my parents were quite poor then), algebra and hang man were my games and pieces of scrunched up paper and hand drawn mazes were my toys. Without realising these were actually maths, spelling, creativity and art. I found school very fun as I could do a lot of things without any effort. I cannot say whether I am 'ahead' of others but I am certainly happier than a lot of people (those who know me will know how cheerful and happy I am), no matter how much work/ stress I have.
That is my aim for my baby (and babies to come!

), a happy go easy personality who can still face reality and endure some pressure and stress.
