Keep trying with the local Leaders...it is back-to-school time and I know that things get a little hairy for some. If you want me to help you find someone just let me know what area you are in and I will check.
It sounds like the SNS might work well for the two of you. There are several moms here who have used one and can give you some pointers, although it is helpful to work with someone directly as well.
I know it can be difficult when faced with questions/remarks about your feeding choices. Lots of moms I know will just use a general remark such as "Every day is a new day for me and ds. DH and I are always continually evaluating our parenting choices and think we are making the right choice for our family at this point. Thanks for asking!" (Subject closed!)
Hang in there, you ARE doing a great job. You just need a pat on the back for all of your hard work! <<<<Pat>>>>. I hope you can find a local LLL group. You can gain so much support and encouragement from moms there as well!
