Jolly catching sight of my own wobbly bulge yesterday as I got out the shower:
“Ohh, LOOK Mummy! What a lovely big tummy you’ve got! It’s even bigger than mine!” He proudly showed me his own firm little roundness.
“Does yours make a good drum like mine Mummy?’

I try to skip out the way, but he was faster.

“Oh, no, my tummy’s better than yours, Mummy. Mine makes a good noise. My hands just squish into your tummy, don’t they?’
