I haven't been out with DP and no baby as yet (tho planning to give it a go as it's my birthday later this month!) but we've had a spate of weddings this summer and we've just taken DD along in the Ergo - not the best for my outfit but at least she sleeps while the party goes on around her and when wakes everyone remarks what a 'chilled out" baby we have This lasts til about 9.30 / 10pm ish when she gets overtired and we make a sly exit before she cracks it thus perpetuating the perception of our 'chilled' princess!
