Keep thinking of going for a fourth 
But we have a goodish car atm low mile etc..we couldnt afford another as we only got it whne i was preg with dc3 (now8mth)
Its 7seats..but seat 6and7 in the boot..do you think its doable to have the children in back row one on passanger seat at the front and one adult on a boot seat..means decresing boot space!
Is this just mad and should i just accpet we cant afford 4dcs
