Our child bike seat was one of the best things Ive ever bought, I was nervous before trying it then within days it felt the most normal way of getting around in the world. It also really helps when you are in a hurry to get somewhere! I probably didnt shop around that much but would strongly recommend the copilot one we have, i think this is it: http://www.evanscycles.com/products/copilot/taxi-child-seat-ec009149. My older son is now getting a bit big for it, although i still took him out on it the other week although he has just turned four. The baby is only seven months and i cant wait until he is a nearer one and I can take him out when son one is not there, am really missing the cycling!
