Hello I really need some advice as see loads of different things online! My little boy is 7 months and weighs 22lb his quiet a big boy! His feet have just started to slightly over hang his maxi cosi car seat and head is at the top! So does this mean I need a new car seat? Obviously I'll still keep him rear facing but I have a 3 door car and usualy have him in the front (passenger airbag is turnt off) are the next stage ones suitable for front seats or not? If not has anyone had one that's easy to use rear facing in a little 3 door car? I'm so confused!! Thank you
