DS2 is 19mp and for the past I can't remember how long - months - has been waking at 4:15-4:20am every morning and won't go back to sleep. He shares a room with DS1 (3.10yo - who is also an early waker - 5/530am) I always end up giving up and bringing him downstairs to avoid him waking his brother EVEN earlier, and end up watching cartoons on fucking Netflix because CBeebies isn't on yet.
Every. Single. Morning this happens. 4:15am. THIS IS NOT NORMAL!!!!!!!!!!
