We have two boys (three and a four-and-a-half) and they share a bedroom. Both regularely wake up at night, either because they need a wee, or they have a bad dream, or they need a cuddle. Sometimes (occasionally) one of them will squeeze in our bed and I'm too tired to put them back in so he'll stay there.
Result: we don't get a good night sleep and get woken up most nights, at least once.
They both slept through the night from 6 months old until they were both about 2.5.
Other parents share the same trend? What do you do to get a good night sleep?
