I just checked on 3rd Pea.
She has discovered she can sleep on her tummy. This is good news for us as it's likely she'll feel secure enough not to need so many snuggles all night. This is especially good news for C, as she is the Pea's snuggle object of choice (with me coming a distant second).
The Pea has decided the best place to be sound asleep on her tummy is horizontal about half way down the bed. She obviously loves her mummy, though, because she is almost entirely on my side of the bed.
While C has close to a full half of the bed to stretch out in snuggle free slumber, I have an approximately 25cm wide strip of mattress and I'm fairly confident that as soon as I lie down little Pea will decide to practice kicking me in the stomach.
I think I might head for the spare room...
