My lo is 20 months, he sleeps 2 hours at nap time and 12 hours at night. I have to wake him at 3 from his nap every week day to go and get his brother from school! One a weekend he very often sleeps 3 hours and goes to bed at 8 instead of 7 but still rises at 7 the next day!! I think 2 hours is average for around this age, hes been doing this for around 6 months now xx
