If I had things my way...

1) Babies would have an on and off switch: turn on in the morning and off at bedtime at parents' discretion

2) All babies would love and want to suck 

3) Breastmilk would flow like water from a tap - not according to demand

4) Pre-pregnancy clothes (yes, that favorite pair of Gap jeans) would fit a week after delivery

5) Doctors would find a cure for colic

6) One can simply pop a pill to overcome postpartum blues

But alas, this is not an ideal world...
