Oh, wanted to add two things.....the first is DD is 21 months old and in the maxi rider we still don't have it fully extended height-wise (and she's average height for her age), with one height position to go. The other thing is DD fit into the seat no problems in a hip dysplacia cast- her hips were splayed out as wide as they could go, and then surrounded by plaster. So not sure where the lady was getting her info from. Hope that helps.
