Liam thought hard but finally decided and think 'Instead of lying to her I should tell her directly that I want to eat sweet porridge made by her milk!'
He said "Mom I know that too. I also don't want to share your milk! Your milk is only mine. But mom I want to eat sweet rice porridge only made by your milk!"
Lilith nodded her head and continued listening to him.
Liam continued "So mom you can do this. First you can make sweet rice porridge with cow's milk for Leah and Celestia! Then you can make a small portion for me using your breasts milk!"
Lilith was surprised but she had already thought something like that before.
She chuckled and asked "You didn't want to let your sister eat sweet porridge made by my milk?"
Liam nodded his head and said "Of course mom! Your milk is only mine."
Of course the thing will be different if they ask him to let them eat with his own mouth.
But he didn't said to his mother.
