I know your youngest child is supposed to go in the back seat of a Phil & Teds but I'm not the only mother I know who put their youngest in the front. I found my youngest didn't much like being down there near to the ground whereas my slightly older child thought it was quite fun. However, whilst I think the Phil & Teds is mostly a brilliant design, I think where it falls down is that a baby who (quickly) grows out of the lie flat section isn't particularly comfortable in the back seat or the front seat. I have baby number 3 due soon and wondered if anyone agrees, has anyone found a good product to add to the front of a Phil & Teds, to make it more comfortable and supportive for a young baby?
