I don't want to be rude, but I think we should be a little more understanding of moms who give their toddlers cow or goat milk after 1 year. For those moms who follow the standard American Diet - they are probably just going along with what most pediatricians suggest today. I'm not saying they are right, they just are doing what they think is best.
Also, not all of us who say we believe in extended breast feeding are actually able to do it. I have been TRYING very hard to nurse my 14 mo. old all summer and she has somewhat resisted me (due to a number of factors). Many of us are full time working moms and have to be away from our toddlers all day. Some of us aren't able to pump and give our toddlers our milk.
The calcium found in other things (veggies, etc.) is not what it should be because the soil in which it is grown is not as good as it used to be decades ago. It's tough to know that your toddler is getting enough calcium without milk.
It really is tough to do our best for our toddlers. Let's support each other and not make each other feel more guilty. JMO
