My toddler has been having a very bad patch of sleep the last 3 or 4 weeks. It's starting to get better now, he's now sleeping through the night again but waking at 4:30 consistently. He seems very tired from this so I don't think it's because he's getting too much sleep. His room isn't too cold and it's pitch black at that time. He's eating well so I don't think he's hungry and I evidence of teething (we are waiting for back molars).
His speech has developed quite a bit in the last week which i think could be part of the sleep disturbance?
What could I be doing to encourage him to sleep longer in the morning? He is 23 months.
