We have a basic car seat for DS (can't remember what it's called but it's red). Supposed to be suitable for up to 13 kilos, but DS's head is just at the top of it now and I can't see it lasting more than a few weeks. We don't have a car but will be going to a wedding at the end of the month and will be travelling by car.
What do we do now? Is he still too little for a forward-facing seat? Are some baby seats more roomy than others?
