I have to say - as somebody who spent twelve continuous years breastfeeding - that I agree with Dr. Jack. Looking after babies, toddlers and young children is tiring. It's not the milk production that wears you out, it's everything else. I know many women who weaned because they thought it would be less strenuous, only to find their babies or toddlers were as demanding and tiring as before, and they'd lost a nice easy way to calm and soothe them. I became convinced of this when one of my friends adopted a baby. Three days after the baby (a 2 month old) came into her life, my formerly energetic and efficient friend was an exhausted wreck. And she wasn't breastfeeding and hadn't been through all the physical changes of pregnancy. I can't tell you how much better that made me feel. I do think this is important, though, because many women who are tired or feeling overwhelmed with the responsibilities of child care, housework and possibly paid work as well are told they should wean because the breastfeeding is what's making them tired. It seems to be considered preferable to pay for formula than a cleaning service or something similar to help a tired mother. . .
