Once baby is here you will have a health visitor and they are able to give you a list of places in your area for baby groups 😊
I’m Stockport based, and there is plenty around. Follow Family Events in Stockport on fb or insta. There’s also Stockport Mumbler which lists classes on sensory, swimming (a few local life leisure), and mum and coffee groups. Pram Pushers is one worth looking up too.
Have you asked your midwife? They should have told you about antenatal classes already
