Definitely felt guided by DD's behaviour when it came to that last day sleep... Found that she was more than happy to be out and about, and we would often lose track of the time and then realise "oh it's 3 o'clock already!" I did go through a stage of her wanting to have a nap at about 4, and in short this was pretty disastrous - she would either think it was her night sleep and stay sleeping, waking at 4am or she would wake up invigorated and not go back to bed til 10pm In the end I felt a bit cruel, as I would make it my mission to not let her fall asleep, and boy did we have some terrible witching hours around 5-6pm. But honestly it didn't last long, she adjusted and started going to bed no dramas 6.30-7pm and sleeping really soundly. Think from memory this started happening for us at about 3, and by about 3.5 it was gone... Think it all depends on the child though aswell, DD hasn't kept still since the moment she arrived
