Congratulations Sarah and yay for a scan date tigger!!
I've started looking at travel systems this week. I really liked the Silver Cross Wayfarer when I was in mothercare at the weekend, but there are some scathing reviews about the wheels online. None of them are recent, and the comments on the reviews say the wheels are much better after they're repaired. It seems a bit of a minefield, good job I don't plan on buying anything until January sales!
