We are early risers too. 4 am for my 3 rd child, it used to be 5 am with my DD and DS1 and I thought it couldn't get worse, how wrong I was! 4am is all kinds of wrong for a person who doesn't do mornings, it's wrong for any person! I have tried it all to try to get my kids sleeping until at least 6am, and it hasn't worked. DD is 6 1/2, so it's been that long since I have been trying to 'fix' it. Nothing works, so I have finally just realised I have to suck it up. Go to bed earlier, or deal with having 5 hours sleep every day.
