I do have to admit, I feel a lot of pressure from other women to breastfeed--and to breastfeed only. I don't understand why, if you choose to use formula, that you are made to feel like a porriah?
You'll find this is the case as you move through parenthood, whether it's breastfeeding; whether you work or not, Let your kids watch TV, have cell phones..... The most important thing is for you and your hubby to be a team on these issues, and to be strong in your choices. If your friends in your mommie groups hassle you, just be strong. Maybe you can't tell them to get lost, but you sure can look people in the eye and say, "this is what's working for us, and I don't need to hear your opinion any more". Or something like that...
