Hi there
Can't believe there are Mums from Bangor on here! I also live in Bangor but have older kids (10 and 3)and have just gone back to work full time, so wouldn't be good for meetups. When my dcs were small I found it wasn't that easy to find out what was going on around, so thought I would put down a few places I used to go.
There are two brilliant Mums and Tots that I attended with my 3 yr old dd - CFC in N'ards behind Cordiners Kitchens. Is run on Mon, Wed and Thur. They have a room which is like a proper nursery - loads of toys, sand, paint, playdough, dressing up etc etc. They do a themed craft every day. Snack time they serve loads of food for parents/carers and kids (although too much for kids maybe!). They have an outdoor area. They have big equipment inside too and cars, etc. Then they have a song time which is done by two brilliant girls (women), with guitar and mike. It does cost £2.50 per family, but really really brilliant. Sad that part of my life is over now! Oh yes and people very very friendly.
Another group is the Baptist (Bethany?) on Gransha Road - more traditional type M&T but really really welcoming to new visitors and friendly. They are on Thur morning.
Also the library on Friday morning have Rhyme Time for Toddlers (babies are there too), which is lovely and free - only half hour but do songs and nursery rhymes and staff are lovely.
Don't know if this is of any help to anyone, but just some ideas if anyone is stuck for something to do. Ok, I'll shut up now!
