DS dropped from 2 to 1 day sleeps about a month ago. So far I've found that if he seems tired, we will just sit in a quiet room and read a book or just a cuddle and chat so he has some downtime but not necessarily a sleep. This gives him a second wind and now we've also added in morning tea - fruit, milk and a rusk type biscuit usually. Then we have lunch between 11:30 and 12. He's really tired by about 12:30 and is asleep for his arvo nap about 12:45/1pm-ish and he usually sleeps anywhere between 2 and 3 hours.
