So you have read all the books, taken notes about the do's and dont's of parenting, you have scouted the local public and private schools, thought about playdate partners and playdate schedules, chosen his music section, video shows he'll be allowed to watch... should I go on?
Remember that you are not just dealing with a baby, you are dealing with a person and as such he will want to affirm himself, make choices, sometimes mistakes. If you try to control his life too much, he will just try to break free from you!
