He usually sleeps from 7-6. Now he is in the habit of waking and not going back off unless in our bed and will wake up anywhere from 4:30-5:30 every day.
We tried co sleeping and their own beds with all three and when it didn't work we resorted back. We only let them in if its going to help but it doesn't seem to. He will not go back to sleep and will just talk or shout and wake the others up.
A later bed time won't help as it will still be a 4:30/5:30 wake up.
