As background, I am on maternity leave and am slightly introverted but still reasonably sociable. I was also on the fence about kids for a long time before I had DS (who is 7 months) so I don't have a huge knowledge of baby related stuff and didn't really think organised baby activities would really be my cup of tea.
Anyway, DS recently started crawling and I thought he was getting a bit bored at home so, against my better judgement, I signed him up for an activity based baby group for his age range (5-12 months).
We went to the first session today, and most of it is instructor led, but there's a 10-15 minute part that is free play. During this free play period, I got chatting to another mother whose DD was using the same play equipment as my DS. It turned out that she and I had a hobby in common.
However, after say 5-7 minutes of us chatting, another woman in the group comes and sits next to me, but with her back to me, plonks her child on the activity equipment and starts suddenly talking to the mother that I was chatting to, in a way that's designed to exclude me (it was clear that she was old friends with the woman who I was originally chatting to).
I just found this bizarrely territorial, and the kind of crap that I hadn't experienced since I was a teenager (I am late 30s). Personally, if I had gone to a group with an existing friend who was chatting to someone else, if I decided to join them, I would have acknowledged that other person's existence, and tried also to make conversation with the other person.
It's confirmed some of my worst fears about baby groups. Did I just get unlucky, or is it this type of thing par for the course at baby groups?
