Childminders,childminders.Renault scenic,car seats.3 along back seat..9mths-11yrs?????

[mum2oliver]

I need 3 car seats that will fit safely along the 3seats i the back of my scenic safely for 9months to 11years..
Can anyone advice?
I know I could go to somewhere to try but just would like to know if anyone could advice now??

I have three Britax freeways on my back seat as they have the narrowest bases, but they are only till 4 years

I have two Britax high back booster seats from ds's 6 and 4 and a Britax club class for dd aged 2 in the back of mine if that helps. They fit fine and the kids say they have lots of space
