Bed time

What time does your little one go to bed /wake up?!

Our son goes down at 7pm and wakes every day without fail at 4am and has done for about 5 months now! I'm interested to know if we are putting him down too early!

I'm now pregnant with baby2 and am exhausted and this routine really isn't going to be sustainable when we have a newborn to look after too!

(He has 1 day nap, 1 hour long, have tried cutting it out and changing the time of it but it doesn't affect wake up time)
