Yes I do! And I'm usually quite confident but hate going to playgroup where I don't know anyone. I've tried the "Oh isn't your baby beautiful" routine and chat for a little while then they go back to talking to the people they're sitting with. Very very cliquey. I stuck it out for a couple of months, just let my ds3 run around doing his own thing but sat on my own throughout the session. Even when I was pregnant with ds4 and there were 2 other preg mums there, they sat in a corner with their heads together most of the time.
Tbh I can't be arsed and although I think my little ones might be missing out, it just seems like too much hard work and I've got better things I can be doing with my time.
