Hi, I'm looking to buy a rearward facing toddler seat as my 14 month old has pretty much outgrown his infant seat. We've got a Vauxhall Zafira, older model so no Isofix unfortunately. The two older children are in the car too, but as there is only a lap belt in the middle seat and they are in high back boosters, we're limited as to where we can put them. Anyone have any experience of this, I'm very confused (doesn't take much!)
