I am nursing my toddler during pregnancy (toddler just over 2 and 25 weeks pregnant) and I barely know anyone else who breastfeeds, let alone a toddler or during pregnancy. (well, one person from the BF group I went to still breastfeeds her toddler) Those I do know who breastfeed or have breastfed only really do so for a few weeks or months and don't have the same parenting style as me. I'm an NHS peer supporter currently, but even there most view breastfeeding as food only, think allowing comfort at the breast is odd etc. 
I wouldn't say I'm 'militant' at all. I do use a pram as well as slings, don't always bed share, but I am child led. Am I likely to meet like minded Mums if I go to the LLL meetings? It would be nice to find some other Mum friends who have similar views. Also, can I attend the baby meetings while I'm pregnant and if so, can I do that with or without my toddler? (I know they have toddler meetings too, but due to the timing of the meetings it's not always possible for me to attend)
