I have a maxi cosi 2 way pearl (bought 2016 new) for my now 2yo DS. He's quite short for his age but already looking very crushed up in the rear facing position and is starting to really complain about going in his car seat. I'm loathed to change his to forward facing - one of the reasons I bought the petal was it said it could do rear facing until 4yo. I've looked in the instruction manual to see if the seat can be moved back in the iso fix base but can't find anything. Is any one else using this car seat still in rear facing for an older toddler? Have you managed to adjust the seat or vase to give more foot room? If so, please could you tell me how to do it?!
