I don't really do Facebook as such. I'm on it, and I have five friends- 3 cousin spread far and wide, my elderly next door neighbour, and my daughter- after she got upset that I didn't include her... I did't until she was 100% committed to a relationship . I have nothing to show on my profile, and a distant shot photo on me aged around 2/3 ish!
We were kind of forced to join when the LA more or less quit all support but recommended a few groups on Facebook!
I do now find it a valuable resource. Obviously the village page is a must . We have a Facebook page for the setting- which the parents find hilarious as I'm so useless at adding bits etc. There a some really good early years support groups on there.
