I just moved into a new flat in a new town. I have an 11 week old dd and don't know anyone yet. Sometimes when I'm out on my balcony I can hear a baby crying from the upstairs flat. Would it be weird to go up there with my dd and introduce myself, on the off chance there's a SAHP who might like a cuppa one afternoon? Or would that be invasive? I probably wouldn't have considered it on London but this is a small town of 9,000 people.
