Several months before BB was born, our realtor in the States gave me a gift: the children’s book Guess How Much I Love You.

It was the first story I read to BB and quickly became part of our nightly ritual – a.k.a., my desperate attempts to get him to go to sleep.

The book still holds a special place in my heart because, just as Little Nutbrown Hare thinks he’s found a way to measure the boundaries of love, the children and I like to fondly one-up each other at bedtime.

“I love you all the way to the moon,” BB will say.

“I love you all the way to Pluto and back,” I’ll respond.

And so on, until we find ourselves doing circles round the Universe.

Recently, though, there’s been an uninvited guest at bedtime: the iPad. BB has managed to sneak it up to his top bunk a few times now to play games under the covers (and with a BYOD – Bring Your Own Device – programme at school, it won’t be long until it finds its way into his school bag too).

My 4yo is fast following in BB’s electronic footsteps, and took our little game to a whole new dimension tonight.

“I love you Mummy,” he called out in the dark. “I love you all the way,” he said, pausing for a second to think how to outdo me…“all the way to the highest level.”
