When our son was born, my wife wasn't sure she would be able to nurse. She thought it'd be a little weird, and we'd heard of a lot of moms who weren't able to for various reasons (low supply, small baby mouth, etc.). So we went into it not sure how long it'd last.
Over the past month-and-a-half we've started taking steps to wean our little monkey from the breast. . . he's starting to look at my wife's breasts and lick his lips in a slightly sleazy way. Pumping in her classroom at school has worn her down and we've been using a nipple shield since day one which eliminates the connivence of nursing. So for a month an a half we've been slowly moving him onto formula (he's down to nursing only once a day in the morning, and doesn't seem to care when we drop a feeding).
The reasons for weaning him are not an issue for us. It's our decision and we've made it. I've heard lots of reasons for breast-feeding. It's less expensive, it's better for the baby, it promotes bonding. . . all bullshit! Only one reason should sway moms in favor of breast-feeding. . .
The smell!
The smell of formula has to be the second worst smell in the world. The first is the smell of formula-fed baby poop. My God it's awful!
I support women whatever way they feed* their baby, but damn. . . I don't think I'd have been able to handle the smell for this long.
*I still will say nursing past one year is a little creepy, and breast-feeding in public is fine, but if you can whip it out in public I'm allowed to ogle.
