Hi, my DH and I want to get into bike riding with the older kids now that they can ride their own bikes. We are having problems however finding something to do with our 11 week old. There are kid carriers out there but they are designed for older kids who can sit up on their own and can hold their heads up. We really need something where the baby can lie down or at least have a good amount of head support. Anyone know of a product which fits this? We're looking more for a pull along "trailer" thing that will attach to the back of the bike.
