I took Pip to see a "lullaby session" every week when I was on leave, it was my weekly treat after his library story time! It's really good, the key is to be prepared. Have everything ready to go - get in early, get the nappies ready to change, take a cocoon or similar for bub to sleep in. Don't be afraid to walk the bub around the back of the cinema if needed - and enjoy yourself!!!!!!!!!
