A cold baby is less likely to sleep...so make sure he's undressed before nursing. Also, try to nurse using the 'football' hold with the baby placed to your side, clutched like a football. This position helped me when learning to get the aerola into my babies mouths.
Barb-the LLL would affirm nursing well into the 2nd and 3rd years if the child is interested. (usually only nursing at night or something.) I wouldn't know how much nutritional benefit it is to the child at that age as they probably don't get THAT much milk...but a little breast milk is better that NO breast milk. What do you all think?
Unfortunately the only downfall to nursing a toddler is that society has it labeled as taboo

...funny how we'll tolerate the rude, cruel, vulgar & sexually explecit in the everyday media, but the simple act of seeing a woman nurse is considered taboo.

Power to nursing women!
