He is such a sweet kid.
Tonight, whilst in the bath, David and I hid and listened to the conversation.
It went like this:
B: "I like it when you say Mum Mum Ma Ryley"
R: "Mum Mum Ma"
(giggles between both)
B: "I know what it means Ryley"
R: (smiles) "Mum Mum Ma"
B: "It means you love Mum"
(more giggles and both of them chorusing together Mum Mum Ma")
There were tears from me.
