Haven't they grown Mildred

Presuming they are the same ones I took the other night they seem to have got bigger awfully fast.
They sailed down the creek leaving mum to bring up the rear but as they got closer they let mum lead the way.
I must go back and make sure there weren't nine the other night.
They are all good at feeding from the mud and didn't seem at all worried that we were looking down on them from the bridge.
