I would like to know if my 16 month old is sleeping too much. He has always been a good sleeper and has slept through the night from 6 weeks of age. For the past few months he has been going to bed at 8.30 and waking anywhere from 11 to 12.30 the next morning. He will then go down for an afternoon nap from 2 until 3.30. This is great for me as I work nights, but I am worried that he is sleeping too much. Can you please tell me how much sleep my son should be getting at this age. Thank you.
