For the last few nights and maybe longer I've noticed that DS is waking around 3 and 5.30am every night. It doesn't take very long to settle him (max 20mins). The wake time can vary by 10-15 mins each night. Last 3 nights have been 2.50, 3 and 3.10. The times aren't EXACTLY the same but the fact they are very close, does this mean its habitual? I've tried to leave him for a bit but his cries start to escalate until I go in. I've read that I should do wake to sleep and Tracy says to go in an hour before. Does it need to be an hour or can it be half hour? Anyone had any success with this? I don't want to find myself up for an extra time in the night.
