I would imagine your babies will fill out a bit more if not get a little bigger as well.
It's hard to tell size from pictures but I feel like our drake (left) is fairly large, our blue is almost the same size as our drake and our chocolate is just a tiny little thing. So I guess with just our 4 it's hard to tell what the normal size is for a full grown runner
Your babies are super cute and so happy having pool time!
