Sorry, IMHO, this topic is very laughable and meaningless.
Are you sure that none can remember hisher 1-2 first years ?
Very true, we all can't remember our 1-2 first years, so are our babies. but remember! NO parents would NOT treat their babies kindly and with all their lives and love!
It isn't about whether-we-should-do-so, but about we-naturally-do-so!
When my daughter was about 1-2 years old, she was a true trouble-maker! she peed on my clean clothes, and sometimes when I was so tired and fell asleep, she wakened me with her nails scratching on my cheeks; I couldn't get a full-night sleep during her first 1-2 years. and yes, it didn't matter whether I treated her well, because she wouldn't remember anything if I treated her in a terrible way. however, It would be IMPOSSIBLE for me NOT to treat her well! that is what we call parents! absolute love for kids, no reason! just nature!
