Thanks...

What do you think is a reasonable amount of sleep for an 8mo?

He normally has 2 day sleeps of 1 1/2 h each and then I try and put him down at around 7-7.30pm. He doesn't go down with much of a fuss but usually wakes up 45min later screaming and then he's hard to resettle. And then he's up through the night as well just for a dummy and can wake anywhere from 6-9am depending on how much time he spent up the night before.
He seems to be staying up around 3+ hours now before he wants to nap....
