Hi Arianna,
Try your local health centre, church notice board or shopping centre for ideas. Often there are meet up’s in coffee shops within shopping centres. used to go to the National Aquatic centre parent and baby swimming classes with my baby and met some mums through that and then we went for walks and coffees etc together after the swim
Jo Jingles are great too, its a fun activity to do with baby and you get to meet other parents – there is a list of their locations on their ad on the right,
I met some nice mums from classes l went to with them. hth
