First, to the original poster. Go, nurse your baby and have a wonderful time at Disney!!
I am mom to seven, six of whom have been nursed and all self weaned before 12 months, including a set of premature twins. I am a nurse and my husband is an md, and it is a fact that the nutritional content if breast milk is superior to formula. And, there are definately reasons (allergies, diabetes, etc.) for women to nurse their babies well through their toddler years.
However, I don't agree that breastfeeding is always the best choice for every mom and baby. I also don't agree that the bond between breastfed babies and moms is any better or different than bottle fed babies and moms. My oldest daughter who was bottlefed exclusively loves and is loved as much as her siblings.
I think that moms who choose to breastfeed OR bottlefeed should be supported in their decision, one way or another. It is a personal decision, not that of the public at large. Moms who choose to nurse should be encouraged and supported in doing that where they are comfortable, not made to hide because someone else might be uncomfortable with a baby being nursed in public. And, moms who choose to bottle feed should not be harrassed because they chose not to breastfeed for whatever reason. They are both moms nuturing their babies, just doing it in different ways, doing what is best for them.
Being a mom is hard enough without others criticizing our choices. My friends and I who are all on COMPLETELY different paths of parenthood try to be SUPPORTIVE when we can and QUIET when we can't. It works really well
And, we have totally found that simple explanations work best when having to explain something to our children that they might not have seen before. Children take in alot from their parents. If we don't make a huge deal out of it, they wont either.
