Hey I've got a 2 year old and a 9 month old would be happy to meet. My mother's group with my first all but died and wasn't really offered one with my second.
Hello I run relaxed creative play sessions in SwaleCliffe Free Church on a Thursday morning 10-11:30 £4 per family. It’s a great way for parents to chat and meet new friends too https://www.wholeheartedlife.co.uk/book-online?category=836e1a11-394e-495e-a1e2-ebc74e19f415
The child health nurse would be able to put you in touch with a parent's group locally (that's how I met the mum's group with my first kid, still going strong almost 2 years later). I'm in Earlwood, with an almost 2 year old and a 2 month old, happy to meet.
