Attachment Parenting Groups in London

I was wondering if there are many parents like me in London area. Me and my DH are bringing up our daughter Mia using the attachment parenting methods. I've learnt the name for this method only recently. I was simply raising my child the way I was raised and never knew there was a special term for this. Our DD is 15 months old already, and I am still breastfeeding. We've co-slept since the first day of her life and have always been carrying her swapping to the stroller (switched to the hipseat few weeks ago).  Most of the parents I know do not share our belief in this child-centred way of life, and I would love to hear from others using gentler parenting techniques.

Thanks,
