Thanks for the replies. A few people have mentioned the maxi micro (which is the one above the mini? Height adjustable?). I have a 3rd child (DD3 1.2y) who is walking. This time next year DD2 will be almost 4y & DD3 will be 2yrs. Would you suggest waiting to invest in the micros then perhaps & getting a mini & a maxi for both girls then. Which means perhaps I just pick up a cheaper 2nd hand 3 wheeler razor (for eg) for now....? Or just get a mini & pass it down next year, or the year after (DD3 will be 3 then...).

Hubby having trouble with the cost...
