Looking for some car seat advice please I have a DS of 2.2yrs and he has a Maxicosi Toby stage 2 car seat. DD is 10m and she has a maxicosi stage 1. She is rapidly growing out of it and we are trying to work out the best strategy for the next seat bearing in mind that we have a ford Focus and we hope to have another baby. Both our kids are tall. Should we buy another stage 2 or one that does stage 2 and 3? Any advice gratefully received!
