Hi, still having a dilemma choosing the right buggy, but think we're settled on the babystyle oyster. However, not sure whether we need the carrycot or whether the seat (which the manufacturer says is for use from 6+ months), laid flat, will be sufficient? We've had a couple of retailers say, the seat laid flat will be okay, however it doesn't appear to lay fully flat when we've tried. Has anyone used the oyster babystyle from birth for their baby without the carrycot and if so, how did you get on?
