My DS usually still wakes once a night for the loo (is almost 4) and if he does he hops in our bed, if he sleeps through he wakes just after 5, so I actually dont mind him waking and coming in with us as he goes straight back to sleep and then sleeps till 6 or 630.

DD slept like a dream until 5 months, I was only feeding once overnight, so your friends luck may change. DD was waking multiple times per night from 5-6 months and has just now only gone back to one wake per night (at almost 8 months) - and co-sleeps with us in a sidecar cot

I think my children are normal Heck, I dont even sleep through the night, I get up for the loo, or a drink too! I'm 38!!
