My partner and i looked for the right car seat for a long time wanting something from birth and rear facing up to 4 yrs approx. Being restricted by short seat belts we found the joie i-anchor which is an i size and is supposed to be one of the safest around. So everything was going well with the seat from newborn but now my son is 4 months and is tall for his age if he falls asleep he slumps forwards. A lot! I went back to Mothercare who didn't really say much and I've contacted Joie who were less than helpful saying just that i might need to buy a neck support (which are not regulated and tested in the car seats and should not be needed for the car seat claims!!) So now I'm left with what i would class as an unsafe car seat and we're being forced to use an infant carrier which my baby gets too hot in!! Anyone had the same/can offer advice??
