Anyone with any practical advice or experience on this before I hit the buy it now button! It is for DS who will be 18 ish months (currently 13 months and not walking yet) and new baby who is likely to be late preterm (34-36 weeks) I like that it has a carrycot. Boot space not an issue, drive everywhere as we live in the sticks so the ability to throw maxi cosi on is great for the school run etc.
