Right, here we are, with authorial comments included (not mine - I haven't been to any of these):
Broomhill Toddlers: good, and four days a week, so you can take your pick. (Broomhill Church, Randolph Rd; Mon, Tue, Wed and Fri)
Garscube Community Playrooms (open all week)
Hyndland Toddler Group (Novar Drive), Tuesdays & Thursdays 10am-11:30am
Observatory Road Groups (including French, German and Spanish groups. English-speaking group is very good - friendly and cosmopolitan!)
Partick Annexe, Thursdays 10am-noon
St John's Renfield Church, Kelvindale, Tuesdays & Thursdays 10am-11:45am
Scotstoun Toddler Group (Scotstoun Parish Church, Earlbank Avenue) seemed good but I've only been once.
