Just curious... why does your son have to be weaning to make you proud of your big boy? If he's still nursing - which is best for him and healthier for you too - he will still be your 'big boy'. If breastfeeding is going well... why wean? The antibodies and immune & development proteins he's getting from breastmilk cannot be duplicated with cow's breastmilk and vitamin supplements.
Just asking....
***For those who commented on my post***
I was a hard working single Mother, either working 2 jobs and or going to school full time and working for the first 5 years of her life. I was still able to breastfeed my child for as long as she wanted, as well as give her regular foods and watered down juice. No cow's breastmilk in our house unless it is needed for cereal or a recipe. I know how hard being a Mother is - probably more than many of you posting here. I recently married 11/20/2010 - after my daughter's 5th birthday. I am now an LPN, and am proud to have allowed my child to decide when she was ready to wean.
