from Jack Newman:
But I want my baby to become independent
And breastfeeding makes the toddler dependent? Don’t believe it. The child who breastfeeds until he weans himself (usually from 2 to 4 years), is generally more independent, and, perhaps, more importantly, more secure in his independence. He has received comfort and security from the breast, until he is ready to make the step himself to stop. And when he makes that step himself, he knows he has achieved something, he knows he has moved ahead. It is a milestone in his life.
Often we push children to become "independent" too quickly. To sleep alone too soon, to wean from the breast too soon, to do without their parents too soon, to do everything too soon. Don’t push and the child will become independent soon enough. What’s the rush? Soon they will be leaving home. You want them to leave home at 14? If a need is met, it goes away. If a need is unmet (such as the need to breastfeed and be close to mom), it remains a need well into childhood and even the teenage years.
Of course, breastfeeding can, in some situations, be used to foster an over-dependent relationship. But so can food and toilet training. The problem is not the breastfeeding. This is another issue.
