There are times when DS sleeps in our bed. We have a QS bed. Neither of us drink/smoke etc, so I am always aware that he is there. I wrap him, so I don't get a finger in the eye, get his anti roll thingo (dunno what it's called) and put him in the anti roll thingo on a pillow (the sort of pillow you sleep on lengthways) between DH and I. He is elevated, so there is no way I can squash him.

He is also further up the bed so his head is the same height as ours. He falls asleep with me on my side breathing in his ear. The heavier I breathe in his ear, the deeper his sleep. The anti roll thing stops him rolling of the pillow.

I don't sleep as well as when he isn't there because I am aware of his presence. DH has to turn over without flayling his arms all over the show. He is also aware of his presence.

When the alarm goes off, we all wake up together - happy families!!

Of course, some nights he stays in his cot, in his room all night, but there is the odd night where he just wants some company.
