Does anyone know under the new child restraint laws a child need to be in a forward facing seat till they are 4. The only forward facing seats that we can find go to 18kg. DS1 is currently 15kg at 2years old so i would expect that he would reach 18kg before he turns 4. My understanding is that the new laws are based on age rather than weight so what will we do when he reaches 18kg and is not yet 4? Is there a forward facing seat that goes past 18kg? We were going to get the maxi rider but have decided against it after getting some expert advice on it. TIA
