We are off on a 3hr car journey soon and our DS with be 8.5mths. He has a backward facing car seat but it seems too small for him - he is a long baby and weighs approx. 25ilbs. I asked in mothercare and they reckon he has some time left it it but I am concerned that it causes his head to drop forward when asleep (it's a graco car seat).
Would it be wirth us getting a forward facing one and any suggestions as to which one?
